Jason, the message you mention has nothing to do with the bug reported here, it is from the color management daemon and in no case prevents a job from printing. The bug reported here is about a problem of the GTK/GNOME print dialog not handling printer driver updates correctly. It only happens when a printer driver gets updated (can happen during a general system update or an upgrade to a new Ubuntu version). We need your error_log (in debug mode, see "CUPS error_log" on https://wiki.ubuntu.com/DebuggingPrintingProblems) to judge whether you are suffering this bug or something else.
** Description changed: [Impact] The problem occurs when the printer's driver package is updated and with this the PPD is replaced and one of the default settings of the queue is not available any more in the new PPD file. Then the setting is prefixed with "Custom." and with this the jobs fail. See comment #15 for more info. [Test Case] - Create a print queue with a PPD. - evince an arbitrary PDF file - Click the print icon - In the print dialog choose the newly created queue and choose some uncommon paper size (not custom). Click "Print". - Check /var/log/cups/error_log, the page size gets correctly received. - Close evince. - - Stop CUPS, edit the PPD file removing the paper size you have selected for your job in the PageSize, PageRegion, PaperDimension, and ImageableArea lines. + - Stop CUPS, edit the PPD file (in /etc/cups/ppd/) removing the paper size you have selected for your job in the PageSize, PageRegion, PaperDimension, and ImageableArea lines. - Start CUPS. - Open the same PDF file again with evince, click Print and then select "Print" in the print dialog without changing anything. - The job fails, in /var/log/cups/error_log you see that the page size is prefixed with "Custom.". With the fixed package installed the job will print. [Regression Potential] The change applies only to saved settings of the print dialog not matching with any of the settings available in the PPD file. In rare cases the fix could fail by mis-understanding the setting and this way not being effective. For options which do not support setting custom values (the vast majority) the patch should always prevent a job failure though.
