@artwaw said in Blurry and strange color when creating barcode using fonts:

@Proton-Phoenix I no longer have access to the Zebra I was using in the past (I changed the company since then).
Zebra printers are a story on their own to troubleshoot anyway...

General approach I used:

make sure the printer is configured properly in the system, with the default page size set to the target page size. query the QPrinterInfo instance for the default page size. use that data with QPdfWriter to render whatever text + barcode I need. remember DPI settings, either set what the manual for the printer says (ideal) or 300 (this didn't end well for Dymo printers I used for a while, needed exact DPI of 204 ;) ). print and enjoy.

In general getting this to work might be lots of trial and error, depending on the brand and drivers. But once it's done right it is literally zero maintenance for years.

<3 Thank you bro for everything <3

@SGaist
now i know how to do it
it was unknown path for me ... that's why i asked but you gave me the right path <3

Really Thank you bro <3

@TheCrowKaka Yes, we now have the same solution running on Windows desktop, Android and iOS, basicly using this method: https://www.kdab.com/efficient-barcode-scanning-qzxing/

@lukas_kosinski would also be great to have more codes - esp Code39 and EAN-Barcodes are essential for my apps

@mcosta Hi,

I'll certainly take a look at it. So I guess it's not only changing the font xD

Thank you.
