Applications rely on the existing printer queues in the same way as command line tools do. There is usually no need to reconfigure the printer for a particular application, because you should be able to print from applications using the available queues.
Some applications rely on the lp command for
printing. In this case, enter the correct command in the application's
print dialog, usually without specifying
filename, for example, lp -d
queuename. To make this work with
KDE programs, enable . Otherwise you cannot enter the print command.
Tools such as xpp and the KDE program kprinter provide a graphical
interface for choosing among queues and setting both CUPS standard
options and printer-specific options made available through the PPD file.
You can use kprinter as the standard printing interface of non-KDE
applications by specifying kprinter or
--stdin as the print
command in the print dialogs of these applications. The behavior of the
application itself determines which of these two commands to choose. If
set up correctly, the application should call the kprinter dialog
whenever a print job is issued from it, so you can use the dialog to
select a queue and set other printing options. This requires that the
application's own print setup does not conflict with that of kprinter and
that printing options are only changed through kprinter after it has been
