Comment 1 for bug 881843

I have attached an example CUPS log to this comment to demonstrate the problem.

Looking at the source more closely, it appears that the initial test for Validate-Job succeeds, but actually using it before printing fails. One very quick way to test this would be to find the line "while(!job_canceled && validate_job)" (1229 upstream), and simply put "validate_job = 0" on the line above this. That should skip the attempt to use Validate-Job. Longer term, this might have to become a configurable option, either globally or per IPP printer.
