To _know_ how to address printerX's trays, you have to have a manual for
printerX, 'read it like a love letter' (thanks Alfredo), and experiment.
You might get lucky with a similar printer (and you can bet that other
vendors bent over backward trying to handle whatever might come down the 'hp
PCL' pipe), but luck goes both ways.
The days of early laserjets were an exciting time, with a new model on the
scene every other month. So what could we expect re consistency? Maybe a
little more than we got, but mostly in the form of available and accurate
documentation - most of the PCL changes I've been aware of have actually
been pretty logical at least at the time; figuring out what the docs meant
was often a bit less than straightforward.
Remember, this is hp, and we're talking about huge dollars in terms of
market share. Prompt and accurate documentation of the de facto standard
would cut into sales thereof, no?
*correct me please someone? As I understand it, the reason hp appears on
virtually all early, and a very good percentage of recent laser printers is
not that hp 'invent'ed them, but rather that hp had PCL, a reasonably mature
and adaptable language for communicating with Canon's new laser engine. How
the contracts betwixt hp & Canon actually worked, I dunno, but hp won the
big prize, industry 'standard'. Other than PCL, hp's contribution to the
laser printer world is marketing (and of course claimed 100% hp-laserjet
compatibility;-)
