Can not print from NC 23.0.6

[FadeFx]

Hi, i have a NC 23.0.6 installation (NextcloudPi) on my RPi4 with Debian Bullseye base, i had printer app working before with my old installation on Buster where i moved my NC installation from, but on Bullseye i can not get it to work anymore, i can print a CUPS testpage, i have allowed www-data on the printer, but i think my actual problem is way before it comes to CUPS. the NC log shows this when i try to print:
