Title: HP Laserjet III as a Postscript Printer
Date:  7/20/90

Copyright 3Com Corporation, 1991.  All rights reserved.

The HP Laserjet III has an optional Postscript cartridge (HP product
33439P) that allows the Laserjet III to be used as a Postscript printer.
However, the Laserjet III with the Postscript cartridge is not completely
compatible with the Apple MD dictionary contained in the LWPREP file.

Symptoms:  When the server is rebooted, it downloads the LWPREP file to
the Laserjet.  This fails with a Postscript error:

   %%[error: undefined; OffendingCommand: 1ab3 ]

If a Macintosh user attempts to print to the Laserjet, the printer will
print the Postscript error:

   %%[ error:  undefined; OffendingCommand: md]

The first error, with the undefined command "1ab3," terminates the
downloading of the Apple dictionary MD, which is why "md" is an
undefined command for Macintosh printouts.  The "1ab3" is part of a
Laserwriter-specific patch that does not need to be executed on the Laserjet
III.  You can modify the LWPREP file to fix this problem.

On 3+ servers, LWPREP is located in C:\3PLUS\3SHARE\LWPREP.  On 3+Open
servers, LWPREP is located in c:\3OPEN\SERVER\LANMAN\SERVICES\MACPS\LWPREP.68
or LWPREP.70.

Use a text editor that can handle text lines up to 256 characters.
Look for the line that contains:

    %%BeginProcSet:  "(AppleDict md)"

Delete the lines that follow this line, up to, but not including, the
line that begins:

    systemdict/currentpacking known

Once you have finished editing this file, power cycle the Laserjet III (to
remove any dictionaries), then reboot your server (to download the new
LWPREP file).  Your Macintosh applications should print properly.
