40 * This allows an OS/2 printer to be specified as an
41 * output using
42 * -sOutputFile="%printer%AppleLas"
43 * where "AppleLas" is the physical name of the queue.
44 *
45 * If you don't supply a printer name you will get
46 * Error: /undefinedfilename in --.outputpage--
47 * If the printer name is invalid you will get
48 * Error: /invalidfileaccess in --.outputpage--
49 *
50 * This is implemented by writing to a temporary file
51 * then copying it to the spooler.
52 *
53 * A better method would be to return a file pointer
54 * to the write end of a pipe, and starting a thread
55 * which reads the pipe and writes to an OS/2 printer.
56 * This method didn't work properly on the second
57 * thread within ghostscript.
