This problem happened a couple more time, but not in a way that I could reproduce. Furthermore I couldn't print plain text files no matter what I tried, with the queue status listing "empty file" and foomatic errors.
I tried adding an additional printer specifying the same remote printer. That printer worked. Comparing /etc/cups/printers.conf I saw that they had few fields different. Changing the non-working printer's Type to match the working definition got it to work, too. (Changed Type from 8433678 to 8433676--is this clearing CUPS_PRINTER_REMOTE?) Both defined printers at the same location--ipp://192.168.1.6/printers/S600. Everything was printing except for chromium browser print-outs. With either printer type the gutenburg ppd does work, and it prints chromium browser output as well. ** Changed in: foomatic-filters (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/734591 Title: foomatic-rip assert failure: printer: options.c:763: build_foomatic_custom_command: Assertion `choice' failed.
