I am wasting a lot of ink printing drafts from KDE apps to HPLIP Printers (shared office, Pagewide 377dw) because the standard KDE printing dialogue does not allow me to specify the print quality. This has do be done manually in printer-settings. Gtk-based applications do offer such an option right away though. The same applies to special settings such as paper type or tray.
Is there any way to expose more options of the Cups-driver in the KDE printing dialogue? Far, far back there was “kprinter” which offered a lot of customizability. Do I have to go back to the kludge of yore and create a new virtual printer for each page setting?
What print options are displayed by lpoptions for the given printer?
lpoptions -p <HP_printer_name> -l
If the required options are present, then it might be viable to create another print queue (effectively second instance of the same printer) with the required options specified in the configuration (/etc/cups/printers.conf) perhaps. Just a thought.
