Opera

Opera for Linux uses Qt to handle the printing. Qt looks in /etc/printcap for available printers, so make sure your printers are listed there.

If you are having problems printing, try adding a custom printer under the "Options" tab in File > Print. For example:

Printer program: lpr

Parameter: -Plp0

CUPS: To print using CUPS, Opera must have access to libcups.so, which is included in libcups. Even if you use CUPS, you still have to have a valid /etc/printcap. CUPS should generate it automatically, but if it doesn't, make sure that this line is in your /etc/cups/cupsd.conf:

Printcap /etc/printcap

Note: libcups is not included by default in some distributions, and may be in developer packages.
