The filter converts the data the user wants to print (ASCII, PostScript, PDF, JPEG, etc.)
into printer-specific data (PostScript, PCL, ESC/P, etc.). The features of the printer are
described in the PPD files. A PPD file contains printer-specific options with the param-
eters needed to enable them on the printer. The filter system makes sure that options
selected by the user are enabled.
If you use a PostScript printer, the filter system converts the data into printer-specific
PostScript. This does not require a printer driver. If you use a non-PostScript printer,
the filter system converts the data into printer-specific data using Ghostscript. This re-
quires a Ghostscript printer driver suitable for your printer. The back-end receives the
printer-specific data from the filter passes it to the printer.
24.2 Methods and Protocols for
Connecting Printers
There are various possibilities for connecting a printer to the system. The configuration
of the CUPS print system does not distinguish between a local printer and a printer
connected to the system over the network. In Linux, local printers must be connected
as described in the manual of the printer manufacturer. CUPS supports serial, USB,
parallel, and SCSI connections. For more information about the printer connection,
read the article CUPS in a Nutshell in the Support Database at
.org/SDB:CUPS_in_a_Nutshell.
►zseries: Printers and similar devices provided by the z/VM that you can connect
locally with the IBM System z mainframes are not supported by CUPS or LPRng. On
these platforms, printing is only possible over the network. The cabling for network
printers must be installed according to the instructions of the printer manufacturer. ◄
WARNING: Cable Connection to the Machine
When connecting the printer to the machine, do not forget that only USB de-
vices can be plugged in or unplugged during operation. The system should be
shut down before changing other kinds of connections.
