xxx I am setting up a Macintosh instructional facility with Appleshare file server and printer server software, a laser printer, and no charge for using the facility. I would like that each printed page to contain the following legend printed in half-tone: "For academic use only: CNR Computer Facility" printed at the very bottom of each page, to discourage students from using our Laserwriter as a substitute for a Xerox machine. How can we do this with the Apple print server software? Jim Bradley, CNR Computer Facility, UC Berkeley

Have this code run outside the normal job loop using the exitserver operator. Download this code to your printer periodically (say, every 30 minutes). The problem with this is that people will eventually discover that if they turn off the printer and reboot it, they will have, at least until the next time the code is downloaded, the original showpage. Once people learn that, they will just power-cycle the printer whenever they don't want the "watermark" to show up. -- Roy Smith, Public Health Research Institute 455 First Avenue, New York, NY 10016 {allegra,philabs,cmcl2,rutgers,hombre}!phri!roy -or- roy@alanine.phri.nyu.edu "The connector is the network"

I am not sure it would work, but how about modifying your LaserPrep
files? Supposedly, someone hacked at it to limit copies, pages/copy,
etc.
It should be possible to modify the LaserPrep file to automatically
set your "watermark showpage" whenever the LaserPrep file is sent
(i.e. after every reboot).
I am not sure of the advisability of this measure, it is just a
thought/suggestion. :)
Hope this helped,

Not being an expert on the Mac, I do have an idea that might get around this problem. I believe when the Mac tries to print to the laserwriter, it first checks to see if the laserprep file has been downloaded. If not, it will download the laserprep file. If somehow the laserprep file could be fixed up so that it printed the required legend on each page, then you would be OK as long as you have control of the laserprep file. This could be accomplished by putting a hard disk on each Mac with the application and the laserprep file, or putting it onto all of the application floppy disks. Of course, if someone learned how it was done, they could change the laserprep and then power cycle the printer. If that Mac were the next to print, then the "watermark" would disappear. I don't know how you would do this, but you might be able to use some other machine as a print server on appletalk and connect the printer to it. Then all the printing would pass through that machine and you would have some more control of what was in the printer. You might be able to accomplish this with a cheapie PC with an appletalk card and the printer on a serial port. You might also be able to do it with a Mac the same way. John Unruh

I think there are programs which don't use LaserPrep. One could, for example, generate their own postscript and then use something like SendPS to download it. -- Roy Smith, Public Health Research Institute 455 First Avenue, New York, NY 10016 {allegra,philabs,cmcl2,rutgers,hombre}!phri!roy -or- roy@alanine.phri.nyu.edu "The connector is the network"

I'm not really sure about the best way to do the implementation for this, but here is some PostScript that will print something similar to what you need. I use this from within MS Word (formatted as PostScript style and placed in the header) to print messages such as DRAFT, CONFIDENTIAL etc. Good luck with this.
