Re: Printers not clearing out
Hi Joe,
Which driver are you using for the 1022N? According
to HP's chart (and direct observations by another poster)
you need to use the LaserJet 6L driver included with 2003.
HP printers supported in Citrix Presentation Server environments

I just helped another person who had issues with the P2014
and my conclusion was that it is *not* TS compatible. Most
of the text below came from my previous response.
These two printers (P2014/1022N) are host based, and as such
are not good TS printers (unless you are using a 3rd party
universal printer driver solution). They will use much more CPU
and bandwidth for each print job when compared to a printer
that has the native ability to understand & process PCL or PS.
Another down side of host based printers is that you do not
have the flexibility to map to a more basic driver like the HP
LaserJet 4. Mapping to a basic driver is a common technique
if the manufacturer-supplied driver is not TS compatible. The
basic drivers often produce smaller print jobs as well and are
fine for many business document needs.
I did a quick test for you to illustrate what I mean. I opened a
43KB text file in notepad, and printed it to the P2014 host
based driver. The document was 12 pages.
The amount of print data that downloaded to my workstation
was 1,487KB!! In addition, CPU usage on the TS was heavy
during the entire time the print job was downloading to the client.
Next I printed the same file from Notepad to an HP P2015
PCL 5 driver (Similar to P2014, *not* host based).
The amount of print data that downloaded to my workstation
was only 128KB!! There was a brief spike in CPU usage while
the 12 pages were spooled from notepad, but then it went
back to 0% afterwards.
If you have several users printing on your TS, using a host
based printer could quickly bring the server to a crawl because
of the CPU and/or bandwidth used.
The above test was relatively basic. Real world printing will
involve multiple fonts, colors, some graphics, which will amplify
the problem.
NOTE: When I ran the test with the P2014 I noticed strange
behavior. After the notepad print job completed downloading
I noticed many "phantom" print jobs accumulating in my local
print queue. In just 30 seconds I had over 100 jobs sitting there.
When I attempted to log off of the server it took several
minutes, hanging on "Executing C:\WINDOWS\system32\wlnotify.dll".
Normally logoffs are instant. I have extended messages enabled
on this test server or else I would not have known where in the
logoff process it was hanging.
Based on my own direct observations and your description of
problems I would say that the P2014 driver is not TS compatible.
