Printer filters

A ``printer filter'':

converts a user file into a data stream that prints properly on a given printer.
handles the various modes of printing that users request with the -y option of the lp(1) command, such as two-sided printing, landscape printing, draft or letter quality printing, and so on.
detects printer faults and informs the print service, which in turn alerts you.

A default filter is provided to give simple printer fault detection; it does not convert files or handle any of the special modes. It may, however, be adequate for your needs.
