Linux – How to delete a printer from CUPS

From the command line you can see the installed printers with this command:

lpinfo -v

You can change the configuration like this:

lpadmin -p <printer name> <options>

You are probably interested in changing the device uri. This should contain the IP address. Change it like this:

lpadmin -p <printer name> -v <new uri>

Printer configuration is stored in /etc/cups/printers.conf You could also look around in there for the current configuration. See the CUPS documentation here for details:

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:

du -hs * | sort -h

If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:

brew install coreutils
du -hs * | gsort -h

From sort manual:

-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)
