DYMO Label Framework JavaScript Library Async Example: Print a label

 Recently did some work to add label printing to an app I have written for Canoe Slalom.

I found it hard to find any examples, particularly async examples.

So here is my code for you to use/abuse as you wish.

My code displays a spinner at the start, which is removed when the label has finished printing. it also enables a submit button. 

My label description is in a hidden form field called label and the address to print is in a field called address.

 <script src="http://labelwriter.com/software/dls/sdk/js/DYMO.Label.Framework.latest.js" type="text/javascript" charset="UTF-8">  

<script type="text/javascript" charset="UTF-8">

function loader() {

// dymo.label.framework.trace = 1; 

dymo.label.framework.init();

}

function printLabel() {

    $('#spinner').show();

var address = document.getElementById('address').value;

  var textArea = document.createElement('textarea');

  textArea.innerHTML = document.getElementById('label').innerHTML;

  var labelXml = textArea.value;


var label = dymo.label.framework.openLabelXml(labelXml);

label.setObjectText("Text", address);

dymo.label.framework.getPrintersAsync().then(function(printers) {

var printerName = '';

if (printers.length > 0) {

for (var i = 0; i < printers.length; ++i)

{

    var printer = printers[i];

    if (printer.printerType == "LabelWriterPrinter" && printer.isConnected == true)

    {

        printerName = printer.name;

        break;

    }

}

}

if (printerName!='') {

label.printAsync(printerName).then(function() {

  $('#spinner').hide();

    enableButton('submit');

});

}

else {

  $('#spinner').hide();

    alert("Could not find Label Writer printer");

    enableButton('submit');

}

});

}

</script>

Label contains the following


<?xml version="1.0" encoding="utf-8"?><DieCutLabel Version="8.0" Units="twips"><PaperOrientation>Landscape</PaperOrientation><Id>LargeAddress</Id><IsOutlined>false</IsOutlined><PaperName>30321 Large Address</PaperName><DrawCommands><RoundRectangle X="0" Y="0" Width="2025" Height="5020" Rx="270" Ry="270" /></DrawCommands><ObjectInfo><AddressObject><Name>Text</Name><ForeColor Alpha="255" Red="0" Green="0" Blue="0" /><BackColor Alpha="0" Red="255" Green="255" Blue="255" /><LinkedObjectName /><Rotation>Rotation0</Rotation><IsMirrored>False</IsMirrored><IsVariable>True</IsVariable><GroupID>-1</GroupID><IsOutlined>False</IsOutlined><HorizontalAlignment>Left</HorizontalAlignment><VerticalAlignment>Middle</VerticalAlignment><TextFitMode>ShrinkToFit</TextFitMode><UseFullFontHeight>True</UseFullFontHeight><Verticalized>False</Verticalized><StyledText><Element><String xml:space="preserve"></String><Attributes><Font Family="Arial" Size="12" Bold="False" Italic="False" Underline="False" Strikeout="False" /><ForeColor Alpha="255" Red="0" Green="0" Blue="0" HueScale="100" /></Attributes></Element></StyledText><ShowBarcodeFor9DigitZipOnly>True</ShowBarcodeFor9DigitZipOnly><BarcodePosition>Suppress</BarcodePosition><LineFonts><Font Family="Arial" Size="12" Bold="False" Italic="False" Underline="False" Strikeout="False" /></LineFonts></AddressObject><Bounds X="322" Y="57.9999999999999" Width="4613" Height="1882" /></ObjectInfo></DieCutLabel>

No network access after windows 10 upgrade

 Recently windows 10 upgraded itself, after the numerous reboots when it was finally finished I was left with no network access.

My broadcom giganet ethernet card refused to work and no amount of dagnostics (which helpfully declare you need internet access) was going to fix it.

As a number of articles suggested I tried 'Netsh network reset catalog' and 'Netsh int ip reset' without any luck.

Disabling windows firewall didn't have any effect. I should have noticed at this point that AVG had vanished.

A ipconfig/renew resulted in the following message.

An error occurred while renewing interface internet

An attempt was made to access a socket in a way forbidden by its access permissions

I eventually noticed in my notifications that the windows upgrade had removed AVG as it was out of date.

If however I went into the firewall there was still an option to enable AVG firewall.

It now became clear that windows had ripped AVG out rather than correctly deinstalling it. You'd wonder why windows update could not simply inform you to update or remove AVG. I guess its part of Microsoft's upgrade at any cost strategy.

I downloaded avgclear from their site using another pc and then ran it to fully remove all traces of AVG.

A quick reboot later and my network card is functioning again.

Invalid certificate being returned for most sites in chrome and edge

As of this morning I could not access most secure web sites using Google Chrome or Microsoft Edge. Every site came up with a secure certificate warning. Chrome kept telling me my connection wasn't private and there was no way to continue.

A wasted morning removing windows updates and some software I'd just installed didn't resolve the issue.

Only by change I noticed AVG listed as the first in the chain when I inspected the certificate in the browser bar.

I then disabled AVG online shield and everything started working again.

As always although AVG was 'up to date' it wasn't. I was running V16 rather than V18. AVG never warns you when a new major version is available.

I duly updated to V18 and everything continues to work.

HP ilo 2 java issues - Solved

Recently tried to connect to one of my HP Servers as I have in the past and I could net get ilo to work even though I tried Edge, IE, Chrome, Opera and Firefox (which used to work) on Windows 10 and Linux Mint. It seems they have all dropped support for Java which means console access is no longer possible.

Fortunately I have as a worst case backup for such situations still have a Vmware VM running XP which I fired up and it worked flawlessly.

However this situation is less than ideal as I'd like to be able to access consoles from my standard desktop or even my laptop.

After many hours of searching and trying things I finally have a solution which works with ilo2 (versions 2.05 thru 2.30)

You need to install Firefox ESR which is the last version of firefox before java support was dropped. The extended support release is designed for administrators like you and me for this very purpose. Better news still is it can be installed alongside your existing firefox so you need only fire it up when needed. It is also available on all platforms.

Please ensure you only install the 32 bit version as the 64 bit version does not include Java support. I suggest you install it in a custom directory.

On Windows 10 you should find it then works fine although you need to remember to put the ip of the secure console in your Java trusted sites using the Java config manager.

You may get Java errors the first time you try and fire up the console window. If you do close the window and fire it up again.

You may also see a grey screen or diagonal grey stripes, if you do scroll to the middle of the console window and click on activate plugin or enable Java. Don't forget to scroll back to the top left of your window to see the console.

Finally you will get untold security messages but just ok them and pass on Java upgrades.

If the console doesn't connect, then again close and reopen and it normally connects the second time.

Successfully working on 32 bit and 64 bit versions of Windows 10 with Java 8 151 and 161 installed.

Firefox ESR also works on Linux Mint with IcedTea (Java equivalent) installed.

Footnote: You need Firefox ESR V52, later versions which it will auto update to will not work. I've also had recent issues with ilo2 2.05 not working so upgrade to ilo2 2.30 if you can.

IBM Softlayer cloud console access using Windows 10

Having struggled for hours trying to get vpn access working with softlayer and then even longer to get Softlayer's java console software to work I finally managed to get console access working with some help from support.

So firstly, ignore anything on their control panel, pptp does not work with windows 10 nor does their java console which requires IE (not edge) or firefox (but not the current version).

Save yourself a huge amount of pain and download Motion Pro client for Windows
https://speedtest.dal05.softlayer.com/array/MotionProSetup_win32.zip
https://speedtest.dal05.softlayer.com/array/MotionProSetup_win64.zip
Having installed that configure all the vpn connections you will need, the vpn servers can be found on this list.
https://www.softlayer.com/VPN-Access
Copy the link for the server you want and then edit it like so:-
https://vpn.mil01.softlayer.com/prx/000/http/localhost/login
becomes
vpn.mil01.softlayer.com
Use the profile add option in motion pro to create a vpn connection, set the host name to vpn.xxxx.softlayer.com, specify your vpn username and password. You should then be able to connect.
If you don't know your vpn username and password, go to https://control.softlayer.com/account/users/vpn in the control panel, your username should be displayed (if not add one), enable automatic SSL access and set a strong password.
Once you have a vpn connection you need to fire up a VNC viewer such as tight vnc.
You will need to find the VNC connection details, to do this go to your virtual server in the control panel, drill down to the device details by clicking on it and then use the action option on the right and select console access. 
Capture the connection and login details from the pop up window that appears and then close it.
Server Name: myserver.mydomain.com
Address: 10.X.XX.XX Port: YYYY
Username: root Password: 12345678
Now start your vnc viewer and enter the remote host and port as 10.X.XX.XX::YYYY, click on connect, when prompted for the password enter it and the console should appear (no need to enter a username).
You can save the details somewhere secure for each server so all you have to do next time is connect up the saved vpn connection, fire up your vnc viewer, select the correct connection and enter the associated password.

windows 10 chrome - The application has failed to start because its side-by-site configuration is incorrect.

So this is perhaps the most unusual error and indeed the most meaningless one I've come across for a while when trying to start chrome this morning.

"The application has failed to start because its side-by-site configuration is incorrect."

Rebooting made no difference

Windows update did install 2017-10 Cumulative update and chrome started logging errors at 3am. From event log I can see the following.

Activation context generation failed for "C:\Program Files\Google\Chrome\Application\chrome.exe". Dependent Assembly 61.0.3163.100,language="*",type="win32",version="61.0.3163.100" could not be found. Please use sxstrace.exe for detailed diagnosis.

Can not remove chrome as even its setup can't be found by windows and when run manually does nothing.

It appears its a visual c++ issue.

The simple solution in the end was to go to https://www.google.com/chrome/, click on download chrome and let it install.

If you want your own cloud storage/backup lima is not the answer

I purchased a lima (advertised as a personal cloud) when they first came out. Ever since then I have been cursing the decision. I should have known, it was advertised on facebook and on visiting the site you are greeted with the news that the 'waiting list' for the product is at 97% and almost full. I see many months on this is still the case, despite this your product will ship just as if it was in stock.

Your receive a little plastic block (blue and white) which has 3 connectors, usb, network and power.

So to the first issue one connector is on one end (USB) and the other 2 on the other (Network and Power) so it doesn't make for a tidy install when you set it up. You'll note the website never shows it plugged in. The power connector can easily fall out or be knocked out so make sure you route the cable carefully.

Secondly it only supports USB 2 drives/USB 2 mode so its not particularly fast.

There is not even an led to indicate it is powered up, connected to the network, logged on to your account, working, syncing or for that matter anything else. Normally I curse everything having an led but in this case it would have been useful.

When you need support you will find you need to see if its 'warm or cold' to determine whether it is powered up, you'll have to check your router to see whether it has an ip address and manually test whether it might be able to access the outside world.

First of all, check that your Ethernet and power cables are correctly plugged in.
Then, could you please answer the following questions?
1. Is the Lima device cold or warm?2. Does the wall socket work fine if you plug another equipment?3. Does your hard drive's led light up when hooking it up to the Lima device? Does it spin?4. Does your router's Ethernet port led light up when you plug the Lima device in? If No: Could you please try to plug your Lima to another router port? Could you also plug Lima with another ethernet cable?
From the router settings:
1. Does the Lima [MAC address](https://en.wikipedia.org/wiki/MAC_address) appear?2. Does the Lima get an IP address?3. Is there a firewall (on your computer and/or on your router)? Does it allow Lima and the Lima app?4. Test the following URLs on a computer connected to the same network as Lima: http://portquiz.net:25211 and http://test-connectivity.meetlima.com/
Please send me a screenshot of the results.

All of this could have been done with an LED which indicated its status and/or the issue. LED off, no power, all fine, on, various number of flashes - various error states.

Support is an laboriously slow process where you have to answer to scripted questions, many of which you may have already covered, be prepared to be patient, repeat yourself and to reboot your router. Once you've done that the information gets passed on to Technical Support who will take some time to answer. Bear in mind you've lost access to all your data whilst this happens.

Thank you for your message. We’re really sorry for the inconvenience. I forwarded your case to our Technical Support Team which will investigate further. I will get back to you as soon as I get an update from them. Their reply time could take some time, so we thank you in advance for your patience. In the meantime, let me know if I can be of any assistance.
In this case it tool a week for Technical support to respond and tell me my lima needed replacing for the second time.


Let me first apologize for getting back to you only now. We received hundreds of questions, and we take the time to answer them one by one. We try to answer personally every single question, so it takes a bit of time. Thank you for your patience. After investigation, your Lima seems to be damaged. We can then offer a full replacement of your Lima package. Before doing so, you will need to follow a few steps listed below. We strongly recommend you to backup any data you could have transferred to your Lima drive. Otherwise, they won’t be accessible anymore. See how to retrieve files from Lima's drive to your computer. The account you created when receiving your first Lima won’t be accessible anymore. Your previous account will be erased so that you can create a new one as a new Lima user. To be able to use the same email address, please contact us when receiving your new device. Have you changed your shipping address since you placed your order? please keep us informed so we will know where to ship your replacement (shipping address + phone number). You don't have to send us back the damaged device, so you can keep it. If you've received a gift with your Lima (earphones), you can keep it as well, as we won't be able to replace it. Your new device will be shipped very soon, you will be recontacted when it leaves our warehouse. Please expect some shipping delays though.

You'll find there is no way of identifying your Lima, no serial number or mac address is printed on it, so if you have 2 like me which are both called 'Blue Lima' by the software you will have to put a label on each one with its serial number/mac address and ip address.

You may find your lima works fine BUT when it does fail you are in for a shock, it has to be sent back and they send you a new one, now you'd think they'd just update your account with the new Lima's mac address, you'd plug it in and continue as before but you'd be wrong.

Bear in mind this is sold as a non techie home cloud. Here are the instructions to replace your failed Lima.

Since it is damaged and returned back, it is not possible to unpair it anymore. The only workaround would be resetting your account so that you can have a Lima and its backup only that are paired to your account.
Here are the preliminary steps:
First, please, eject your Lima Drive from Lima Menu > Preferences > Status as described [here](https://support.meetlima.com/en/articles/203938719-How-should-I-power-off-my-Lima-device). When the hard drive is confirmed as ejected, you will see a confirmation message. This may take a minute.Do not forget to [backup all the necessary data](https://support.meetlima.com/articles/207426143-How-to-retrieve-files-from-Limas-drive-to-my-computer) you copied in your Lima space before you uninstall.
1. Uninstall your Lima apps from all your devices. Need help to uninstall the apps? Check [this article](https://support.meetlima.com/hc/en-us/articles/204931205-How-to-uninstall-Lima-) in our Knowledge Base.2. Unplug the ethernet wire and wait for a minute.3. Unplug your HDD.4. Unplug the power supply.5. Replug the ethernet wire.6. Replug the power supply.7. Plug your HDD into your computer and format it (to NTFS for Windows or HFS+ for Mac). Keep it unplugged for the time being.
Please get back to me when all these steps have been performed so that I can delete your Lima account.

So to replace a faulty Lima you have to copy all the files off it, format the drive, they have to delete your account, then set up a new one, configure the limas and finally copy all the data back.

You will have also lost any files which were in the process of being loaded to the lima when it failed and are presumably in the cache on your computer, well at least they were until you remove the app as instructed above and deleted your account.

Suddenly you wonder wonder what happens if Lima Technolody Inc goes bust, your lima won't work without your account details stored on their server (so much for your own cloud) and all the data stored on the drive is encrypted, so from what I can see if they go bust you say bye bye to all your date stored on it. Presumably if they are for any reason offline you may not be able to use your Limas either?

I originally bought the product as I thought it would be a fit and forget storage and backup solution, as I bought 2 limas.

It took over six months to get an answer from support how to configure 2 Lima's in a configuration without using upnp, in fact I worked it out myself in the end and they eventually confirmed that it would work.

I had confirmation from our Team, to connect 2 Limas with port forwarding, please follow these steps: - Manually redirect port 25211 to one of your Lima, - Please use the port 25212 to the second one.You can use any ports between 25211 and 25215 for your Limas. The Limas will eventually figure it out by themselves (but may take 5-10 minutes) This is relevant to do it manually only if you plan to do a manual redirection. If you are using UPnP/IGD or NAT-PMP, it's automatic. Please do not hesitate to get back to me if you have any further question.
upnp is commonly disabled as software can create security holes in your router without you knowing. In addition its common to have a secure area and a non secure area on your home network. If you do have a separate secure area you'll need hairpinning/loopback on your router so devices behind the firewall can access the Limas. Unfortuately upnp does not support this.

If you are lucky you can define permanent dhcp addresses for the Limas on your router and the port mapping outlined above and everything will work 'eventually'.

It would have been nice to have a simple way to allocate a name, ip addresses and port to each Lima  permanently.

Similarly a simple piece of software could allow you to perhaps diagnose what is wrong with it. There is a diagnostic dump feature in the Lima app on windows which you send to support as I have done many times but without any response.

The windows software seems to take an age to determine the status of the Limas and then a few minutes on it might change its mind. More recent versions seem more accurate. That said there is little indication there is anything wrong with your lima, the task bar icon just changes colour so it could be weeks or months before you notice a fault, you might notice the pop up notification but as it disappears within a few seconds you might not.

The linux version has no gui so you've got to be happy with the command line.

The android version appears to need you to start it to perform the sync and used to eat the battery on my phone.

Forget using the Lima app on a HD pc like a surface pro, the font used is so small its pretty impossible to read anything.

You'll need fine finger control when trying to check the status of uploads too as you have to hover over the different coloured slices of a status bar to see what's what, the slices being proportional to the size of the drive, even then its very vague and there is no way to see what is actually waiting to go.

On a security note your devices might decide to talk to each other through a 'free' relay, on the face of it all the data is encrypted but the whole point of these devices was that the data did not leave your control, now the data is being routed via a relay server located god knows where and controlled by god knows who. There should be an option to disable this feature.

Suffice to say I've had my Limas for 18 months or so now, I've had 2 fail and I've not trusted them with any of my data yet as they are simply too unreliable.

All in all it was a clever idea but it should have stayed on the designers bench until it was fit for purpose. With some sort of status indicator, better software, some form of proper diagnostics, proper support for non pnp environments/secure environments and some thought to easily replacing a faulty unit this could have been a really good product particular when run as a pair.

Mine are most likely just going to be dumped in the parts bin and await recycling.
