We've kept the name "Generic postscript printer" for the PPDs we use for nearest and thinlocal. We should probably have something related to ThinLinc here to avoid confusion with any system drivers.
It is also an incorrect name for thinlocal as that is a PDF driver, not PostScript.
Verified that these names showed up in the printer queue.
Looks good. The names are visible in CUPS' settings, as well as GNOME's printer settings. It isn't shown in printer dialogs as far as I can see.
