Hi all,
I use LuaMetaTeX 2.10 20220918 + ConTeXt LMTX 2022.09.11.
Here's a tiny test document, I disabled PDF compression but it also
doesn't work with the default settings.
\setupbackend[level=0,compresslevel=0]
\starttext
Just a line of text.
\stoptext
When I print this "directly" (i.e. sending the raw PDF to the printer)
on a Ricoh MP3053 or on a Samsung CLP-680DW, I just get an empty page.
Just to add some more data points, I tested the attached MkXL file on
two printers, and the file printed perfectly on both.
Printer 1:
Brother HL-3170CDW
Printed via running "cat test.mkxl.pdf | nc Colour-Printer.local 9100"
Printer 2:
HP M227f LaserJet
Printed from the PDF file on a USB stick
Neither printer is anything fancy; they're both fairly inexpensive home
laser printers. I've got a much older Brother laser printer that I may be
able to test with next week.
Sorry I can't be of more help.
Leah and I are zooming in on the issue. It might relate to wrong font
matrix default behavior in the pdf printer driver, and GS got a fix for
that long ago, so maybe old printers with not-updated drivers can be
affected.
Once we're confident that we can catch it Leah (who does the low level
introspective testing with viewers, printers and tools) likely will
report on it and there will be a test file for users to test if what we
do is okay before we apply the safeguard.
