PRINTCAP(5)
NAME
printcap − printer capability data base
SYNOPSIS
/etc/printcap
DESCRIPTION
Printcap is a simplified version of the termcap(5) data base used to describe line printers. The spooling system accesses the printcap file every time it is used, allowing dynamic addition and deletion of printers. Each entry in the data base is used to describe one printer. This data base may not be substituted for, as is possible for termcap, because it may allow accounting to be bypassed.
The default printer is normally lp, though the environment variable PRINTER may be used to override this. Each spooling utility supports an option, −Pprinter, to allow explicit naming of a destination printer.
CAPABILITIES
Refer to termcap(5) for a description of the file layout.
