Package: cups-filters Version: 1.27.0-2 Severity: important Hi,
since “some” time (few weeks maybe, I guess the 1.27.0 upload), I can't print on my Brother HL-5250DN network printer (which was working just fine earlier). The printer is laser monochrome, and I always was able to print color and monochrome stuff, conversion was happening just fine. Now, when I try to print, nothing happens and I guess an error in the logs about: W [04/Feb/2020:21:28:45 +0100] [Job 570] Grayscale/monochrome printing requested for this job but Poppler is not able to convert to grayscale/monochrome PostScript. W [04/Feb/2020:21:28:45 +0100] [Job 570] Use \"pdftops-renderer\" option (see README file) to use Ghostscript or MuPDF for the PDF -> PostScript conversion. First, it's really not obvious from the log *which* README this is about, and I had to dig a little before finding it was the one from cups-filters. Then, I tried to set pdftops-renderer-default to various options (gs, pdftocairo) using: lpadmin -p printer -o pdftops-renderer-default=<foo> but it didn't work. With: - gs: nothing prints, but nothing happens in the logs - pdftocairo: same error message than without any option - pdftops: same error With mupdf it does send something to the printer but the results shows: ERROR NAME; undefined COMMAND; ° OPERAND STACK; and in the logs I get: W [04/Feb/2020:21:34:29 +0100] [Job 573] Level 3 PostScript not supported by mutool. Downgrading to 1.26.2 from testing seems to fix the problem (I still have the log entry, though, it seems, so maybe it's unrelated).
