Printing direct still uses the spooler service is some regard. When
printing direct, we eliminate GDI and EMF (enhanced meta file) as the
problem during rendering to send Printer Description Language (PDL) data
directly to the device without first writing to the disk.
Printing direct can also circumvent some Antivirus applications that
interfere when generating driver temp files and spl files.
The Print Processor (getting it correct this time) handles page counts,
booklet, and N-UP options. I'm curious if changing the print processor to
Winprint corrects the issue. So if the poster returns, please change the
print proc to winprint and try the repro.
I'm not too worried about HP blaming MS. It's the support group and they
generally still don't have a clue about the Vista driver head to toe duplex
issue on 20+ models. The HP developer here did send the info to the deskjet
division. I did not see any page count issues for the inbox drivers (nor
any third party drivers) in Vista RTM or Vista SP1. So far this is the sole
report.

Windows GDI
Print Processor
The spooler monitors the current print jobs and the target printer to
determine an appropriate time to print a job. Once the spooler determines
that a job should be printed, it calls the print processor. The print
processor is a DLL that reads EMF records and uses the graphics engine to
convert them into DDI calls.

HP has not seen the endless print job. They are aware of the page count
issue. What application is their question.
Subject: RE: Vista Ultimate print spooler printing too many pages. counts by
3
Here's what I know:
This seems like two issues are being lumped together as one: inaccurate
spooler page count and print job being multiplied unexpectedly.
I've never seen the driver multiplying the actual printouts. It would be
interesting to see what app they use. But the spooler page count has been an
issue for a long time. I believe all Mombi drivers with preanalysis has the
same issue of displaying more pages than it's printing. ... has been looking
into a fix but it is not possible to fix without a major change in the
architecture.

I really appreciate the information in your two messages. I hope the OP
comes back into this thread but he has started another on and I'll
check that and chastise him appropriately <g>
I wish I understood as much as you do about the innard workings of
these things but I appreciate the information and have flagged and
printed the information.
In case it helps you find the other post he made here is part of your
post in it. Unfortunately using an OLR I can't give you a link that
will work for you.

try one of the HP OfficeJet drivers that is included in Vista. If you
can
print a legible test page attempt the multiple page document printing
using
this driver.
Run Add Printer , Local Printer, Select the same port as the other
device,
compatible driver, ... Finish
