This looks amazing! I'll bookmark it in case I have PNG/PDF labels in future.

I currently have the problem that Dymo changed their tray application/print from web solution to be pretty much useless, so I bought Zebra printers and came up with my own "JSON to label" thing [1]. Just now it’s a mere proof of concept.

Very nice work. I'm surprised at the lack of tooling for label printers. You've put together an elegant solution.

Thanks!

Wow okay I just spent a lot of money switching out EPL printers for ZPL ones as I could only find a library to convert PDFs into ZPL[1] and nothing much on EPL. I could have hand coded the labels but generating PDFs in Jasper Report Server gives much better tooling and flexibility.

Also there is a very handy online ZPL render[2]

But this tool is magical. I'll be using this in the future.

One of the nice things about the Windows print spooler is you can send different data types on any queue. So one application might send GDI and another raw print data. This is useful as the GDI calls are page oriented but for receipt printing you want something continuous.
