porrey / virtual-zpl-printer Goto Github PK

Hi,
First of all, I like to congratulate you for this wonderful tool!

I'd like to share with you a couple of thoughts, just in case you find them interesting...

Sometimes I get a label layout, designed with another more general software.
Transforming it into something I could feed to a ZPL printer means several iterations: ZPL code, preview, compare, change, and back again.

In the label preview, I can think of two features that would speed up that process a lot.
If I were able to set a background image, to compare the printed label with the desired label, and a grid (in dots/mm/inches) to check dimensions, then I think I could do the above process even with my eyes closed.

If you could add that features, I'd be very grateful!

Thanks in advance,

Carlos

Describe the bug
When running in debug mode on Visual Studio 2022, an InvalidOperationException occurs with the message:
Unable to resolve service for type 'Diamond.Core.Repository.IRepositoryFactory' while attempting to activate 'VirtualZplPrinter.ViewModels.MainViewModel

To Reproduce
Steps to reproduce the behavior:

1. Open ZPL Printer Solution.sln with Visual Studio 2022
2. Rebuild solution
3. Start in debug mode

Expected behavior
The application should start without any error

**Desktop: **

• OS: Windows 10
• Visual Studio 2022

Is it possible to save the output as PDF instead of PNG?

it would be very useful

http://escpos.atwebpages.com/base64html.php

Look at that web service, i am testing this way with jquery

$.post('http://escpos.atwebpages.com/base64html.php',{esc:btoa(esc_pos_raw_data),width:344}).done(function( data ){
    console.log( "Data Loaded: " + data );
    addLabel(data)
});

You send esc/pos data as raw text on base64 encoding, and returns the label on base64 html

Hello,

thank you very much for your software !
I just installed the lastest version and I have a 404 when testing the label ?
maybe we are not able to contact the labellary api ?

Kind regards,

Simon Poidevin

I ran the installer and was able to get the active printer started, but I don't know how to make my applications recognize it as a ZPL printer. Are there additional steps?

Hello,

The application sent an error when trying to print one ZPL

but in another viewer is working fine

this is the ZPL

ZPLSample.txt

Exist a log for checking the issue ?

Thanks

Could you add a few options? Here is what I would like to see:

1. Run the program at startup
2. Minimize to tray.
3. Tray minimize at startup

And what about translation to other langs? Can translate to Ukrainian.))

Thank you in advance for your work!

Is your feature request related to a problem? Please describe.
When you are testing labels with alot of data the api can't response,
Maybe if you have a custom endpoint with self server can change the endpoint to get the labels,

Describe the solution you'd like
Add option to change the api endpoint

When you remove all printer => you can't add new printer

When you launch the app
==> Sequence contains no elements

Hello Porrey I accidentally became aware of your project. I am currently developing a Zebra Tool solution with another developer. Your project would fit well with it. Also you might be interested to work on our project as a whole. https://github.com/BinaryKits/BinaryKits.Zpl

When editing printer configuration and setting the Label Height/Width settings, the program takes into account the system locale regional format settings.

So if the windows regional format uses comma as a decimal separator, it will only allow to enter Label Height/Width with a comma.

So label height 4,5 instead of 4.5.

The program then uses the value with a comma in the API URL it sends Labelary and comes back with a 404 response.

To Reproduce
Steps to reproduce the behavior:

1. Go to "Additional date, time & regional settings" in Windows control panel
2. In "Formats" tab, go to "Additional Settings..."
3. For "Decimal symbol" enter a comma.
4. Press OK
5. Open Virtual ZPL Printer
6. Edit Active Printer Configuration
7. Enter Label Height or Label Width with a decimal number (example: 2,5)
8. Save
9. Press Start
10. Press Test and send

Expected behavior

A valid print label.

I would like to be able to print a "label" immediately after receiving it on a regular label printer that does not support EPL/ZPL. Will such a feature be implemented, or, is it already available?
Thanks in advance for a positive answer))))

Describe the bug
When you set the label in millimeters this does not save correctly

To Reproduce
Steps to reproduce the behavior:

1. Go to labels and create new one
2. Select millimeters and save
3. If you close and open again the value is not same has saved

Is your feature request related to a problem? Please describe.
I have a Zebra ZD421 printer in which I have installed (downloaded) and mapped some custom fonts:

^CWG,E:DIN000.FNT ^FX Dinot Bold 10
^CWH,E:DIN001.FNT ^FX Dinot Regular 7
^CWI,E:DIN002.FNT ^FX Dinot Bold 14
^CWJ,E:DIN003.FNT ^FX Dinot Light 8
^CWK,E:DIN004.FNT ^FX Dinot 7
^CWL,E:DIN005.FNT ^FX Dinot Bold 9
^CWM,E:DIN006.FNT ^FX Dinot Bold 7

Describe the solution you'd like
I want to preview my label using the fonts installed in my printer, all my labels will use only those fonts, not any of the default fonts from my Zebra printer. Also, my goal is to save the label in png to be able to display in my form of my application, not externally.

Describe alternatives you've considered
If there is any, please advise.

THK you for your soft!
But it crush every time after printing...
v 3.2.0
Win 11
I print with this code:

^XA
^LH0,0
^CI28

^FO95,160^A0N30,20^FD002463 ^FS
^XZ

or any other text on this code....
No information about crash in logs, but I add it.

In addition, there is an error in the program window after launch:

Thank you in advance for solving the problem!

After running the installer for version 3.0.1 and attempting to run the application, the following error appears.

Dismissing the error (by clicking the OK button), opens the app. However, adding label settings is not possible. This error renders the app unusable.

Describe the bug
If you are using a test windows they seems block some actions,

Can't paste a custom ZPL code, also can't add new lines, the "enter" button seems locked

To Reproduce

1. Click on test
2. Write new lines with enter it dosent works
3. Or you want to pase code with CTRL + V

Currently, the virtual ZPL printer uses a default file naming convention when saving print jobs as .png files. However, it would be useful to have the ability to pass a custom file name to the virtual printer, so that the generated .png files can be easily identified and organized.

This feature will be useful for applications that need to generate multiple ZPL files with different names.

Hello
Trying some test prints today and I am getting a Labelary service error "Not Found". Is your application using the labelary API? There may have been a recent update. Thanks

Thanks for this tool! This saved me a lot of time testing automotive labels. Cheers

I tried to make Virtual ZPL Printer work with Z* Browser Print.
On my PC it didn't work, and I found that it was caused by an exception during the stream reading.

I replaced in TcpListenerClientHandler (near line 90)

while ((numBytesRead = stream.Read(data, 0, data.Length)) > 0)
{
		ms.Write(data, 0, numBytesRead);
}

by

while ((numBytesRead = stream.Read(data, 0, data.Length)) > 0)
{
		ms.Write(data, 0, numBytesRead);
		if (numBytesRead < data.Length)
		{
				break;
		}
}

And it seems to work better. But not yet 100%.
Not all labels come in Virtual ZPL Printer, and sometimes I have errors between my web site and Z* Browser Print.
(no error in Virtual ZPL Printer)

(Sorry I'm not familiar enough with Git to make pull requests.)

I don't know if I'm the only one having problems with this configuration with Z* Browser Print.
