Adding a filter to the print service
You can add a filter to the system after the filter is defined.
To add the filter to the system after it has been defined, use one of the following commands:
/usr/sbin/lpfilter -f filter-name -F filename
/usr/sbin/lpfilter -f filter-name -
The first command gets the filter definition from a file, and the second command gets the filter definition from the standard input. A filter-name can be any string you choose, with a maximum of 14 alphanumeric characters and underscores.
If you need to change a filter, reenter one of the same commands. You need provide information only for those items that must be changed. Items for which you do not specify new information remain the same.
