Come on, Mr Headrick! No false humility, please! You know how much you
deserve all those compliments and so much more.

Hey, this certainly is an interesting ressource -- LOTS of forums! --, but...

since Dewaine has already intervened in this thread, we might as well
continue here, don't you think? I'm surprised you don't see his post,
since we both have supernews as a provider.

Dewaine has already made a suggestion about downgrading to a former PCL
driver. VERY unfortunately, the 1012 doesn't even use a PCL driver. And
the problem, recognized worldwide, it seems, is that it just won't
print... continously, without off-on recyclings, with a server OS, be it
Linux, Mac OS X and even, I read, Windows server.

So the question, I suppose, boils down to this: how come the Laserjet 1012
refuses to print properly with any server OS? Surely somebody at HP knows
why the 1012 presents such an enormous /bug/ and the way to fix it. I
really don't think Dewaine will be much help this time. This is clearly an
HP issue.

Kind regards!

Could you provide some more details of your issue? What OS are you using?
What model computer? How connected?

http://www.linuxprinting.org has a little more information on this.
They say they solved the "personality" problem in their driver by always
sending a string of eight bytes as part of the job. However, that was
discovered by checking the output of the Windows driver--presumably what
you already have!

It's almost a "host-based" printer. There's probably little to be done
other than pestering HP for a cure. From what I've seen on the HP
support forums, it looks like it may be a ROM bug in the printer.
Whether HP will fix this, or even is able to fix it without replacing
the printer, remains to be seen.

The problem of the "Unsupported Personality: PCL" was finally solved by
Carl Michal (michal at physics dot ubc dot ca). By analyzing the output of
the Windows driver he found out that after the BeginSession operator in
the beginning of a PCL 6 job a special sequence of 8 bytes has to be
added. He added it by a filter to the output of GhostScript's "pxlmono"
driver and from then on the printer worked.

Yeah, yeah... some 8 bit sequence. Very helpful... for HP, maybe.

They've been pestered since this printer is out, it seems.

Yes, a bug...

I don't mind them exchanging the printer. It's not my problem.

It seems it's not really ýmy issueý. Remember, Google is your friend:

I use Linux, which is supported by HP, I believe, but it seems the
problems happens on every server OS.

My computer is a clone with a Gigabyte GA-6VXC7-4X board. The printer is
connected directly through the only interface, usb. Can you think of a
more standard set-up?

GP
