Since upgrading to openSUSE 11.4 (x86_64) KDE: 4.6.3 I find that any changes made in the KDE Printer → Properties → Margins dialogue with Konqueror, Kate, Kwrite, etc. are not persistent. Such changes are persistent in openSUSE 11.3 (x86_64) KDE: 4.4.4.
Consequently I must open the Printer → Properties → Margins dialogue and change the default margin setting (4.23 mm) four times (TBLR) for each print job.
A similar issue with non-persistent duplex printing was solved by installing system-config-printer but that does not provide an option to reset the default margin settings.
I have made the usual searches and checked the printer pages in the SDB. There are some related bug reports on openSUSE, KDE and QT bug tracking systems that make interesting reading (!) but I did not find a user level solution for non-persistent margins.
I would be grateful for some feedback on this issue. Are others experiencing similar printing problems? How are the default KDE print margins set and can they be changed?
