Recently I have run into issues printing to my Minolta-QMS PagePro 1250E black&white laser printer, supposed to support PostScript Level 2 (emulation).
The printer has started to print ASCII text, apparently PS source code in a staircase pattern on several sheets (before I abort). This is the case for all kinds of output/sources.
I use the attached PPD for the printer, which is working fine on Mac OS X and on Windows and had been working OK a few months ago on linux. After running into issues I have also used the PPD in the default repository, which does also not work.
I have tried ghostscript as filter as well as poppler. I have attached PS output generated with cupsfilter for poppler 0.24.1, ghostscript 9.09 and Mac OS X (cups 1.63 on linux, cups 1.6.2 on Mac OS X).
When sending the generated files to the printer with netcat the Mac OS X one prints just fine, whereas the files generated with poppler and ghostscript do print the staircased ASCII output mentioned before. I cannot pinpoint after what changes/updates in cups/poppler/ghostscript linux printing started to fail, but it appears to have been caused by some changes in the past two months.
I have run cupsfilter on Ubuntu 12.04 for comparison (cups 1.5.3, poppler 0.18.4, ghostscript 9.05)
Using gs for pdftops in cupsfilter results in the first page printing correctly, poppler's document is printed completely after halting on the printer after the first page, but this continues after continuing the printer (maybe due to page format mismmatch?)
I have attached the ps files again
