Both “print.ps“ and “print.pdf” can be displayed correctly using “gs”, i.e. apparently KDE4 can produce both correct PostScript and correct PDF. Then print the same page from Konqueror4 to a CUPS “test” queue created like this: /etc/cups/cupsd.conf: FileDevice Yes rccups force-reload lpadmin -p test -P /usr/share/cups/model/Postscript.ppd.gz -v file:/tmp/test.ps The file “/tmp/test.ps” which is created cannot be displayed by “gs”. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I wonder why it works when printing directly to “col_3_2_03”. Does the file format KDE4 uses depend on the CUPS queue it prints to? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I have doubts that cups can influence this behavior. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What does it help to ask the summary as a question again? Anyway, use the source, luke: if(d->use_default_engine && d->outputFormat == QPrinter::NativeFormat) { if (QCUPSSupport::cupsVersion() >= 10200 && QCUPSSupport::printerHasPPD(name.toLocal8Bit().constData())) setOutputFormat(QPrinter::PdfFormat); else setOutputFormat(QPrinter::PostScriptFormat); d->outputFormat = QPrinter::NativeFormat; } with other words, it prefers PDF over Postscript if Cups is recent and has a PPD for it. This is in line with what cups itself advocates: /usr/share/doc/packages/cups/help/spec-postscript.html While PostScript is currently the defacto-standard print job file format/language for UNIX-based applications, it is slowly being phased out in favor of Adobe's Portable Document Format ("PDF") which offers many advantages over PostScript. MacOS X uses PDF as the primary print job file format, and we expect Linux to soon follow. The bugreport doesn't mention a single reason why submitting a job as PDF is a bug, or which problems it causes (other than that printing fails if pdftops is broken). the PDF renderer of Qt is a lot more advanced than the PS renderer (which only supports PS level 1 with a lot of design problems). It does make sense to me to default to the output format that the Toolkit can support well, because it offers the features it needs, especially if it is the same format the underlying printing framework advocates as the default. Therefore the only resolution is INVALID, sorry. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The assumption of your code (comment#10) might be valid for cups-1.4 or later, but for now (cups-1.3) I strongly encourage you to use PostScript only. Using PDF is a time and resource hungry way, as its done now in CUPS: "PDF -> PS -> printer specific" instead of "PS -> PS -> printer specific" Debugging is usually impossible (PDF is a binary blob, PostScript can usually be understand). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
