Filter Type

The LP print service recognizes fast and slow filters, as described in Types of Filters.

Slow filters that are invoked by printing modes (using the lp -y command) must be run on the system from which the print request originated. The LP print service cannot pass values for modes to print servers. It can, however, match a file content type (specified after the -T option of the lp command) to a content type on a print server. Therefore, if you want to activate special modes on a print server, you must specify content types that permit the LP print service to match input types and output types.
