Selecting Print in non-KDE apps - very long delay when connected to network
I am running Slackware 12.1 with both KDE and Slacky Gnome desktops. Primarily I use KDE and some of the Gnome apps.
CUPS network printer attached to a server -this is also a Samba server for windows machines - no problems.
Printing from KDE apps works perfectly - no delay. No delay printing from non-KDE apps when not connected to a network - before activating network interfaces - see note below.
When connected to my network, selecting Print in non-KDE apps (OpenOffice, Thunderbird, Seamonkey, Firefox, Adobe Reader 8, etc) causes a delay of about 5 mins before the printing dialogue shows. After that, printing works perfectly. In the case of OOo, my desktop freezes completely for that time. But, other non KDE apps only hang and I am able to select Kmenu and other apps, while waiting for the print window to show.
I have tried all sorts of probable fixes from various threads and LQ; e.g. uninstalling java, setting the OOo Generic Printer to Postscript driver 1, and Grayscale, turning off GTK styles and fonts in KDE and stopping cups, and so on. All futile; until recently all of this was working fine, as configured.
Note: If I #ifconfig down, the problem remains despite disconnecting the network interface. So something is still going on in the background.
I don't know if anyone else has had this problem - I can't trace back to the point where it started to happen.
Once again having come to an impasse, I am resorting to LQ for answers, which fortunately is infrequent. Most times however, having come to this place I find that the solution is basic - the wood for the trees - what am I missing?
