lp, lpd - copy a file to the line printer
lp [file ...]
Each file argument to lp is send to the line printer to be printed.
Standard input is read and printed if there are no arguments. Lp
executes /usr/lib/lpd with each file as input. Lpd puts the file in
/usr/spool/lpd and starts printing the jobs on /dev/lp unless another lpd
is already running. If 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. Lpd simply
assumes that you know what you are doing. (dumb, eh?)
Note: Don't do anything with a file until it is printed, 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.
Information about a job.
Associated file to be printed.
/etc/termcap The 'lp' entry describes the printer by the "li#" and
"co#" fields. By default 66 lines (li#66), and 80
lp(4), termcap(5), termcap(7).
Not spooling a world readable file may not be such a smart idea.
A formfeed should be printed and the printer reset after a job full of
escape codes, but this may cost paper.
