PRINTCAP

NAME

SYNOPSIS

DESCRIPTION

The default printer is normally lp though the environment variable PRINTER may be used to override this. Each spooling utility supports an option, -P printer to allow explicit naming of a destination printer.

Refer to the "4.3 BSD Line Printer Spooler Manual" for a complete discussion on how to setup the database for a given printer.

FILTERS

p       pr | if regular text + pr(1)
none    if      regular text
c       cf      cifplot
d       df      DVI (tex)
g       gf      plot(3)
n       nf      ditroff
f       rf      Fortran
t       tf      troff
v       vf      raster image

The if filter is invoked with arguments:

if [-c ] -w width -l length -i indent -n login -h host acct-file

The -c flag is passed only if the -l flag (pass control characters literally) is specified to lpr. The Width function and length specify the page width and length (from pw and pl respectively) in characters. The -n and -h parameters specify the login name and host name of the owner of the job respectively. The Acct-file function is passed from the af printcap entry.

If no if is specified, of is used instead, with the distinction that of is opened only once, while if is opened for every individual job. Thus, if is better suited to performing accounting. The of is only given the width and length flags.

All other filters are called as:

filter -x width -y length -n login -h host acct-file

where width and length are represented in pixels, specified by the px and py entries respectively.

All filters take stdin as the file, stdout as the printer, may log either to stderr or using syslog(3), and must not ignore SIGINT .  

LOGGING

Error messages sent to the console have a carriage return and a line feed appended to them, rather than just a line feed.
