I am working on an Apollo DN3000 running DOMAIN/IX. Connected to it is an Apple LaserWriter. Since I also have a Mac at home, I would like to be able to upload PostScript files to the Apollo and print them out on the LaserWriter. What I have been doing is using the command-K trick to generate a file which includes LaserPrep as a header, followed by my print file. I then transfer this file to the Apollo, and feed it to the LaserWriter. The yellow light flashes, indicating that some processing is going on, but no page is ever printed. Does anyone know what I might be doing wrong? Please answer by mail and I will summarize to the net. Thanks in advance. Sebastian Seung

The lpr command on SUN/OS states that if the special characters '%!' are found alone on the first line, the contents of the file are sent unfiltered to the LaserWriter. Using this command (lpr) I got the above described results. A QUICK HACK A quick and dirty solution is to use a terminal interface program (like tip or cu) on the LaserWriter tty-line (this will enable XON/XOFF flow control) then send the file to the same /dev/ttyx either by using 'cat' from another terminal or by using the raw file transfer facility of tip/cu itself (tip uses ~> <FILENAME> I believe). This works although it bypasses the spooler which should be temporarily disabled while the cludge is attempted. I intended reporting the problem to SUN as a bug in lpr, but if same is happening on Apollo I am at a loss to know the cause (of course they might be entirely different problems - knowing Apollo - they probably are :-)) --alen the Lisa slayer (it's a long story)
