I really don't see how the switch from drivers to printer applications is an improvement. All the existing drivers have to be ported to the new interface to essentially emulate the IPP protocol. And now, instead of being able to configure printer options through the existing graphical CUPS frontends (or just set them temporarily in the individual application, which most applications support nowadays), you end up with a CLI as in the old lpr days, e.g.: https://www.msweet.org/lprint/lprint.html#printing-options https://www.msweet.org/lprint/lprint.html#setting-default-options or at best, a GUI provided by the printer application in some arbitrary toolkit, which will likely be GTK for Gutenprint (forcing KDE Plasma users to use a GTK application to configure their printer) and Qt for HPLIP (forcing GNOME users to use a Qt application to configure their printer). Instead of a standardized interface to configure printer options, every printer application now has to reinvent its own one. >From the end user perspective, the new approach brings only disadvantages. >From the driver developer perspective, it means a lot of porting work. The only ones who will benefit are the CUPS developers, who will have successfully outsourced their work to other projects that now have to do their work for them.
