Lprint is sensitive to both system hostname and server name about lprint HOT 3 OPEN

The blabbering above was of course coincidental. Now I am getting that error regardless of the hostname:

May 13 14:09:22 shopship.local lprint.lprint-server[694]: I [2024-05-13T11:09:22.916Z] [Client 12] Validate-Job client-error-attributes-or-values-not-supported (Unsupported print-quality enum value.)

I will continue investigating and will report when I find anything.

from lprint.

Printing succeeds if I set -o cupsPrintQuality=Normal:

lp -d VevorPi -o media=101x220mm -o cupsPrintQuality=Normal -o print-scaling=none debug_output_shipping_label_20240513105329.pdf```

Setting the same option as default does not help:

sudo lpadmin -d VevorPi -o cupsPrintQuality-default=Normal

from lprint.

OK, so you are having a bunch of problems, and not all of them related I think.

The CUPS "lp" and "lpadmin" command issues are specific to CUPS and not LPrint. The "print-quality" option is what IPP calls an enum value - 3 is draft, 4 is normal, and 5 is high or best quality. The strings are only supported for the "cupsPrintQuality" option which is part of the PPD options. The default PPD option name is "DefaultcupsPrintQuality", not "cupsPrintQuality-default"...
