Convert to ZPL II?

[Braindea7]

Question

Hey, I like your package it works very well, but lately we have some problems with the direct print of pdfs on a GK420d. I think it's related to the generated ZPL format. If I change the ZPL format in the Zebra Printer Setup Tool to "ZPL I" it works again. Do your package generate ZPL I or ZPL II code? If it generates "ZPL I" code, is there a way to update it to "ZPL II"?

Hi @Braindea7,

this library was built for ZPL II based on this programming guide.

What might be an issue is the selected encoding/compression. There are four options and some printers might not support each one.

You can test the different encodings either in your source code (EncodingKind in zplOptions) or with this website: https://www.sungaila.de/PDFtoZPL/

I will check different Encodings tomorrow :)

Thanks a lot for your quick help!

Please reopen this issue if changing the encoding did not work.
