IPP Everywhere generic CUPS driver doesnt work with lprint #74

Closed Oberonc closed 1 year ago

Oberonc commented 2 years ago

Test page is printed successfully from the web interface of lprint. a PNG file is printed successfully from the command line using lprint.

Printer: Zebra ZD420 OS: Ubuntu 20.04 LTS PAPPL: 1.2.1 (latest release) lprint: latest from git

When I add IPP Everywhere generic driver I encounter 2 problems:

  1. After adding the printer when I try to print a test page it crashes (I run it again with valgrind for extrq information) valgrind.txt
  2. When I try to print a PNG file using CUPS (same PNG that can be printed using command line lprint) I get an error: badrequest.txt

Can you attach the locally-generated PPD file from your system? This obviously should not crash but the CUPS side is sending a 4961x7016 bitmap instead of the expected 456x429.

Closing; please re-test and if the problem still occurs then attach the PPD file from /etc/cups/ppd.
