I'll have to try this out with a real printer - ghostpdl doesn't not show any problem with gs 8.70's pxlcolor output. So it is either a firmware bug with your's printer's PCL XL implementation or two bugs in the ghostscript/ghostpdl family - one for pxl code generation and one for rendering. The latter is a bit unlikely though. Created attachment 5917 [details]

This is the print out as it is intended to be
I tried various combinations of printer-built in fonts, type1 vs. ttf fonts etc. but it the problem is entirely size related. When using commonly used font sizes like 10, 11, 12, 14, 16 everything prints fine, but as soon the fonts size exceeds a certain size, characters after a color change are either not printed at all or in a wrong color. See the attached files. Created attachment 5920 [details]
Colorbug.odt
Source file with type1, ttf and otf (outline) fonts. The problem is only font
size related.
Please note that while it's a Samsung color printer it uses the PCL 6 driver on Windows as the default printing language instead of proprietary SPL All those openoffice, etc docs are irrelevant - the only way you can get anybody (most probably me, since *if* it is a problem, it would be under 'PXL driver' which belongs to me rather than 'color' which belongs to Michael, but I suspect firmware) to deal with it is if you can reproduce the problem by-passing openoffice/cups, etc , and *preferably with a HP printer*, with this sequence of action: e.g. with a pdf or a ps file, http://launchpadlibrarian.net/37672963/Leseblatt.pdf gs -dNOPAUSE -dBATCH -sDEVICE=pxlcolor -o /tmp/file.pxl Leseblatt.pdf cat /tmp/file.pxl > /dev/usb/lp0 (or wherever your printer port is). If you can reproduce the problem this way, please attach /tmp/file.pxl . This is embarrassing. It obvously is my pritners firmware which is buggy. I created the raw pcl-file as desribed and sent it to various PCL-capable color printers in the office - they all print fine! This bug can be closed ... buggy printer firmware of reporter. Please close the downstream Ubuntu bug report as firmware bug with Samsung's implementation of PCL XL as well. If the Samsung printer prints anything else different from HP or others, we'd like to hear about it - Henry and et al may make that into a business opportunity... Downstream bug report is updated now, thank you for investigating this. |
