So I need to ship back some defective merchandize. The vendor sends me a link to a UPS return label, I open it in Firefox, and try to print it. The printer is an HP 1320.
When I try to print it, the printer blinks happily for a few seconds, but stays quiet, and Fedora tells me that the print job completed succesfully.
I try a few variations. Tell Firefox to print to a PDF file, then open it in evince, and try to print it. Same results. Tried having Firefox print to a PS file. Tried using pdf2ps on the PDF file. Tried a few other things. I forget exactly what I tried, but on one particular attempt the printer woke up. I got all excited, until the printer ejected a single page, with a single sentence "This print job requires a PostScript Language Level 3 Printer", and completely blank otherwise. Very funny.
I finally got the label to come out by having Firefox print to an SVG file, opening it in document viewer, and printing it. That worked.
HP 1320 is a postscript printer, but it looks to me like some PDFs (not all, I can print most PDFs without any issues) contain Postscript features that the printer does not support. Anyone know if there's a way to get CUPS to handle that correctly.
