Labelary service error about virtual-zpl-printer HOT 15 CLOSED

Yes this uses Labelary. I just tested the latest code as well as the latest installer and I was able to get a label. Perhaps their service was down or offline?

Hello, same issue on my side. I have tried running as admin and there is nothing showing in event viewer. Running Windows 10 Pro 64bit.

Can you provide more details to help troubleshoot?

Same issue here.

It's only happend when "Label Units" is changed to 'Centimeter' or 'Milimeter'. With 'Inch' works like a charm.

I have updated the code to resolve the 404 issue when selecting MM or CM. The issue was caused by too many decimal points in the URL after converting the values to inches. The URL is formatted to use two decimal points. Version 1.0.12 is the latest version. The installer has been updated as well. Please let me know if this resolves your specific issue(s).

Hi. Grate thank for this app! But I have same error. If use SM or MM. And same error if I use on Inch for example 0.7 or 1.5 Inch.

This issue was resolved in the latest version (1.0.12). If you have a new issue please open a new request and detail the steps to reproduce the issue.

I have latest version (1.0.12), but have same problem...

from virtual-zpl-printer.

I am unable to reproduce the issue. It would be helpful if you could outline the steps to reproduce the issue (I may be missing something very simple). I'll fix the issue as soon as I can identify it. Thanks.

Hi there, I'm seeing a similar problem using the Virtual ZPL printer from the installer (version 1.0.12). I'm running this through Zebra's Browser Print Service (https://www.zebra.com/us/en/products/software/barcode-printers/link-os/browser-print.html). The Virtual ZPL printer is configured in Zebra's tool, but when I try to print a label, I get an error from BrowserPrint and when I check Virtual ZPL Printer I see the "Labelary Service Error".

The printer is configured to 127.0.0.1:5900 with 4x6 inches and 8dpmm if any of that helps. I haven't tried going into the source yet but that's my next stop.

EDIT: Well, in this case, it looks like the ZPL we are passing in is bad. I swapped out our ZPL with some of Labelary's sample ZPL and It works like a champ. Maybe there's an opportunity to change the "Not Found" error to something more descriptive? Though the response code from Labelary is in fact a 404...

At any rate, with valid ZPL this seems to work well, which is great.

Thanks. Can you post the bad ZPL you used here so I can test/reproduce the issue?

from virtual-zpl-printer.

I ran the following test:

1. I installed the application from the latest MSI
2. I edited the **Samples/6x4-203dpi.txt** file in the install folder by removing a large portion of the text to. are the ZPL invalid
3. started the Virtual ZPL printer and clicked Test

Here is the result:

The message returned was "ERROR: You requested the 1st label, but the specified ZPL doesn't generate any labels". I will try to work this into the label.

Hi, it actually wasn't ZPL, it was a Zebra printer function command (~HQES) to get printer status. Looks like this code is doing a health check on the printer before sending the ZPL. Sending that to Labelary fails to return a label as expected so the behavior is all correct from the printer side.

That said, I think the message above is clearer and probably would have pointed me in the right direction sooner.
