mupprnt: print output from Mup music publisher
mupprnt provides a way to print Mup output on your printer. The file is Mup input. Any other Mup options can be given, except -C, -E, -f, -F, -l, -m, -M, or -v, which don't produce print output.
Under UNIX, if the environment variable COPIES is set to a number, that number of copies will be printed. Otherwise only 1 copy will be printed.
You must have mup in your PATH. You must have ghostscript (gs or gs386.exe) in your PATH.
