Hello,
When starting kdeprinter again, and this time, selecting another printing system type that the default (=CUPS) then selecting again CUPS, it displays "localhost:631" (server:port) just below the printing system selection field. And the error message did never appear on the next runs of "kdeprinter". My understanding is : So, I suppose that if the former "kdeprinter" was configured for using "lpd" before in a "stable" distribution, if I then installed the last version of "kdeprinter" in "testing", a config file located somewhere reminded the "lpd" configuration and library path, until I selected the printing system in the drop-down list. Many thanks to the people who tried to understand the issue. That bug could probably be marked as completed. Alain ROOS
