Change the option with lpadmin:
lpadmin -p queue -o Resolution=600dpi
3 Check the new setting:
lpoptions -p queue -l
Resolution/Output Resolution: 150dpi 300dpi *600dpi
When a normal user runs lpoptions, the settings are written to ~/.cups/lpoptions.
However, root settings are written to /etc/cups/lpoptions.
14.6 Printing from the Command Line
To print from the command line, enter lp -d queuename filename , substituting the
corresponding names for queuename and filename .
Some applications rely on the lp command for printing. In this case, enter the correct
command in the application's print dialog, usually without specifying filename . For
example: lp -d queuename .
14.7 Special Features in openSUSE
A number of CUPS features have been adapted for openSUSE. Some of the most
important changes are covered here.
14.7.1 CUPS and Firewall
After having performed a default installation of openSUSE, SuSEFirewall2 is active
and the network interfaces are congured to be in the External Zone which blocks
incoming trac. More information about the SuSEFirewall2 conguration is available
in Section “SuSErewall2” (Chapter 13, Masquerading and Firewalls, ↑Security Guide)
and at http://en.opensuse.org/SDB:CUPS_and_SANE_Firewall_settings.
14.7.1.1 CUPS Client
Normally, a CUPS client runs on a regular workstation located in a trusted network
environment behind a rewall. In this case it is recommended to congure the network
interface to be in the Internal Zone, so the workstation is reachable from within the
network.
14.7.1.2 CUPS Server
If the CUPS server is part of a trusted network environment protected by a rewall,
the network interface should be congured to be in the Internal Zone of the rewall.
It is not recommended to set up a CUPS server in an untrusted network environment
