Hello Len,
Thanks for the good (and thorough) lesson. So, a laser printer that
stipulates capability of HQ1200, but does not mention Postscript, may yet be
Postscript capable? (the printer in question is a Brother HL-2140, printer
of choice for the former owner of the print server I bought); since I
mentioned it, both my downstairs Macs (a DA G4 running 10.4.11, and a G5
running 10.5.5) can easily see the print server (via Bonjour and IP
address), but cannot negotiate the printer, my suspicion being that it is
not Postscript capable. That's the only drivers that Print Utility offers
when configuring the printer that resides at that IP address, and I
discovered a very-modestly stated aside from D-Link re: its Mac
compatibility to that effect (Print Server in question = DP 311U). I am
trying to verify if the Brother HL-2140 is Postscript capable to assist me
in confirming that this is my problem - no PS capable printer.
Many thanks,
Dana
