NAME

xf − transparent filter

SYNTAX

/usr/lib/lpdfilters/xf

DESCRIPTION

The xf filter is a transparent filter. The filter simply concatenates data directly to the printer. The xf filter may be used with any printer. This filter allows device specific escape characters and control sequences to reach the printer.

There are no command line arguments passed to the xf filter by lpd and the filter does not maintain any accounting information.

The xf filter should be specified in the xf field of the /etc/printcap file.  For further information, see printcap(.). It is invoked when the −x option is used with the lpr() command to print a job. Prior to its invocation the filter specified in the of field is invoked to print the banner page upon completion it is stopped and the xf filter sends the job to the printer.
