My university has several Macs attached through the AppleTalk Network to several printers, one of which is a LaerWriter Plus. A problem has arisen in that everyone is using the LaserWriter for everything including draft copies. I read recently on the net that there was a way to burn a password into the LaserWriter EEPROM so that not everyone could use it. How is this done? How do you enter the password after it is burned in so that you can use the LaserWriter. Also, is there a way to change Chooser to include a password that must be entered before a new printer can be selected? Thanx in advance.

Does anyone know how to reset the password on a LaserWriter? This is stored in the EEROM, and is normally 0, but our password somehow got changed to an unknown value last week. This prevents our macs from using the LaserWriter, since they must give the password before downloading the quickdraw code. Unfortunately, to reset the password to 0 via postscript, you need to know the current password! According to an old news item, the only solution is to disconnect the EEROM so that the LaserWriter will use the default parameters. If anyone has done this before, I would be very grateful for any info, eg: where is the EEROM located and what is its part number?

Does this mean there is a password system on a Laserwriter that can be used to limit access to the printer? Can it be used with Laserspool or some other spooling software? > > Thanks, > John Pritchard > Internet: john@latcs1.oz.au UUCP: uunet!latcs1.oz.au!john -- --------------------------------------------------------------------------- Mats Sundvall +46/18174583 Biomedical Center mats@bmc1.BMC.UU.SE University of Uppsala, Sweden psi%24020010197020::MATS ---------------------------------------------------------------------------

I pulled the EEPROM and zeroed it out to fix this problem. I don't know a better solution. Of course, you need a suitable EEPROM programmer.

Thanks to Mike Berger for the solution, I have now installed a socket for the 2804 EEPROM, so we can replace it when it happends again without wearing out my nerves desoldering the beast. According to our SA, the problem happends when you send a TEX job that is too big for the page. TEX assumes device truncate and the LaserWriter assumes software truncate, the result is some memory overflow which clobbers the EEPROM. In the past, we've found the test page flag turned off/on and the copy counter reset to some random number. However this time it was more drastic, the password register was hit. If this is correct, does anyone know of a solution to stop it from happening again? The LaserWriter is connected to the Pyramid through the RS232 port and to several Mac Plus and SE's on the AppleTalk. It is used from the Pyramid mainly for TEX work. Philip P.H.
