How to maximally insult Avery in the shortest amount of time

Make it not work properly when I print a PostScript file to a PostScript printer.

Oh yes, CUPS, that means you. You and foomatic and gnome-cups-manager and foomatic-gui and gutenprint and hpijs and... libsensors?! All of you. Yes, you. All of you in the ridiculously overcomplex newfangled Linux printing stack who can't do what "lpr" used to do in its default configuration with no filters installed. I hate you all.

Also, the "Print Test Page" button doesn't actually do anything, even if your printer is configured correctly. That was a really funny joke also. Ha ha. See me laugh.
