CUPS Not pre-rendering PostScript

[Mike McCarty]

I have an HP870Cse, which I'm sure you are all getting tired
of hearing about. I have three queues set up for that printer,
one at 300dpi greyscale (default), one at 600dpi greyscale,
and one which is two up 300dpi greyscale (color cartidges are
just too expensive, IMO). Each of these is set up in the
GNOME Print Mangager for pre-rendering, since the postscript
interpreter on that printer is S-L-O-W (like 30 minutes per page)
while transferring a graphics image is acceptably fast (like 4 pages
per minute).

But I find that only the first two actually honor the pre-rendering.
If I print to TwoUp, then it does indeed print two pages side-
by-side on the page, but it takes 30 minutes. If I use mpage,
I get 4 pages per minute again.

Is anyone aware of why that would be or what I could do to
correct that?

Also, I'd like to do some two-sided printing. This printer does
not have a duplexer, so I've been investigating using mpage or
psmandup for that. Does anyone have experience using these
in this manner automatically by setting up the queue to use
them directly?

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!

I assume by the Gnome Print Manager you mean system-config-printer.
This program just does not work properly in a CUPS environment.
Set up your printer using the CUPS web interface 
and I think you will find the results will be more to your liking.

Yes, though I start it usually by clicking on the printer icon.

Ok, thanks for the advice. Er, how do I enter the CUPS web
interface?

Google turned up this...

Is this what you mean?

Ok, I tried that, and it doesn't even have as many options as
does the system-config-printer. In particular, it doesn't know
anything about pre-rendering.

It may not Mike, but what it does do, is right.

Probably so. But it didn't change anything in the setup that
I could find, except a few lines saying what tool did the
setup. In fact, I can't find anything that "prerendering" changes
in any of the files documented by CUPS, and I read every word
of documentation I could find on my machine, which has the
CUPS docu installed. I now know the layout of a .ppd file
and could create one by hand, if I had to, not that I'd
*want* to :-)

But I know it's somewhere.

The places I found it using Googls were all Red Hat related,
so I guess it's a Red Hat thing, not a CUPS thing. Also,
prerendering does not do what I thought (based on what I heard,
that is) if the Red Hat documentation is correct. What the Red Hat
docu says is the *unusual fonts* get prerendered (I guess to
images) and then the postscript is massaged to make it
all postscript level 1 (no 2 or 3), but the output is still
postscript.

I know this: Turning "prerendering" on turned print jobs
which took 30 minutes per page into jobs that took 0.25
minutes per page, but not for "two up" printing, and I still
don't know why. I also know that the output from mpage does
essentially the same thing, and also prints at 4 ppm when
printed via my "non-two-up" 300dpi queue for that printer.

My guess is that it is behind CUPS where this is happening,
in the back end. Maybe I'll have a look at the source
for HPIJS and see what I can find.

It's actually a foomatic thing.

Ahh. (What's foomatic?)

I certainly shall. And in the immortal words of Bilbo Baggins,
