71.3 Printer CUPS Admin
20200213
CUPS provides a convenient command line to administer printers. We can identify available printers with:
$ lpinfo -v
...
network dnssd://Brother%20HL-3040CN%20series._pdl-datastream._tcp.local/
network socket://192.168.178.26:9100
network lpd://BRN001BA9236DC1/BINARY_P1
...List installed printers and the device URI.

To specify a PPD for the printer:
$ lpadmin -p lp4 -P /usr/share/ppd/Brother/brother_hl3040cn_printer_en.ppd
$ lpadmin -p lp5 -P LEXC750.PPDThe PPD file is copied into /etc/cups/ppd/lp5.ppd, for
example.
Printer options (for a printer with a corresponding PPD in
/etc/cups/ppd/ can be viewed with:
Options can then be set with:
These options are placed in /etc/cups/lpoptions. The same
options can be set using the web interface. The web interface is
indeed somewhat easier to use, and it modifies the PPD file directly
(e.g., /etc/cups/ppd/lp1.ppd) rather than using the
/etc/cups/lpoptions file!
Printer options can also be accessed directly from the command line when printing, if the printer’s PPD supports the option. For example, the HP LaserJet 4050 driver (from hp-ppd) supports n-up printing and watermarks:
