- .TH LP 1
- .SH NAME
- lp, lpd - copy a file to the line printer
- .SH SYNOPSIS
- .B lp
- .RI [ file " ...]"
- .SH DESCRIPTION
- Each file argument to
- .B lp
- is send to the line printer to be printed. Standard input is read and
- printed if there are no arguments.
- .B Lp
- executes
- .B /usr/lib/lpd
- with each file as input.
- .B Lpd
- puts the file in
- .B /usr/spool/lpd
- and starts printing the jobs on
- .B /dev/lp
- unless another
- .B lpd
- is already running. If
- .B lpd
- finds any character in the input that it doesn't know how to handle then it
- will print the rest of the file without any special treatment. This also
- means that no formfeed is sent after the file has been printed to force out
- the page.
- .B Lpd
- simply assumes that you know what you are doing. (dumb, eh?)
- .PP
- Note: Don't do anything with a file until it is printed,
- .B lpd
- only makes a copy of a file in the spool directory when it is not world
- readable. If it can be read then it is printed directly.
- .SH FILES
- .TP 20
- .BI /usr/spool/lpd/job XXXXX
- Information about a job.
- .TP
- .BI /usr/spool/lpd/tmp XXXXX
- Associated file to be printed.
- .TP
- .B /etc/termcap
- The 'lp' entry describes the printer by the "li#" and "co#" fields. By
- default 66 lines (li#66), and 80 columns (co#80).
- .SH "SEE ALSO"
- .BR lp (4),
- .BR termcap (5),
- .BR termcap (7).
- .SH BUGS
- Not spooling a world readable file may not be such a smart idea.
- .PP
- A formfeed should be printed and the printer reset after a job full of escape
- codes, but this may cost paper.
- .PP
- No banner page.
