/*======================================================================
print routines
Functions having to do with printing on paper and forking of spoolers
In general one calls open_printer() to start printing. One of
the little print functions to send a line or string, and then
call print_end() when complete. This takes care of forking off a spooler
and piping the stuff down it. No handles or anything here because there's
only one printer open at a time.
