No better idea than just raising the cups loglevel, but I doubt it'll provide anything useful. Perhaps check dmesg? > I read the cups-filters docs in /usr, but it looked as if all the conversion > magic for the image would be done in the background. Yes, it's done by a cups filter. Since apparently some of the picture did show up, that did happen fine. > E [16/Apr/2022:14:50:28 +0200] [Job 9] text conversion pipeline pdftotext > -raw - - | file2brl -p -Chyphenate=yes > -CliteraryTextTable=en-us-brf.dis,en_GB.tbl,de-g2.ctb,braille-patterns.cti > -CinputTextEncoding=UTF8 -CbraillePages=yes -CbraillePageNumberAt=bottom > -CpageNumberBottomSeparateLine=yes -CprintPages=yes -CprintPageNumberAt=top > -CpageNumberTopSeparateLine=yes -CpageSeparator=yes -CpageSeparatorNumber=yes > -CcontinuePages=yes -CcellsPerLine=29 -ClinesPerPage=27 | | addmargins > failed > > The embosser just emitted an empty page. > It looks a bit worrying that there are two pipes in the conversion command. That's odd indeed.

Mmm, I'm not getting any issue with: echo 'Hello, world!' | file2brl -p -Chyphenate=yes -CliteraryTextTable=en-us-brf.dis,en_GB.tbl,de-g2.ctb,braille-patterns.cti -CinputTextEncoding=UTF8 -CbraillePages=yes -CbraillePageNumberAt=bottom -CpageNumberBottomSeparateLine=yes -CprintPages=yes -CprintPageNumberAt=top -CpageNumberTopSeparateLine=yes -CpageSeparator=yes -CpageSeparatorNumber=yes -CcontinuePages=yes -CcellsPerLine=29 -ClinesPerPage=27 It does print "HEQO1 _W6". In strace there is such bogus stat call, but after that it tries to open files one by one too. Which version of liblouis is that? Samuel
