I also have this problem. This is IMHO a bug in the usb backend (no
backward compatibility), or at least something we should be catering
for on upgrades (or at least clearly documenting as an upgrade issue).
The solution is to modify the printer and choose the "proper" USB
device. For example, I used to use "usb:/dev/usb/lp1", but with the
new CUPS "usb://EPSON/Stylus%20C60" is the . CUPS 1.2 works fine with the
latter, but not the former.
Check by running the USB backend:
$ sudo /usr/lib/cups/backend/usb
direct usb://EPSON/Stylus%20C60 "EPSON Stylus C60" "EPSON Stylus C60 USB #2"
"MFG:EPSON;CMD:ESCPL2,BDC,D4;MDL:Stylus C60;CLS:PRINTER;DES:EPSON Stylus C60;"
