Hi Jason,

It’s been years since I’ve built/supported a 4.5 environment, but remember that
there were a couple of known issues. You’ve already mentioned that you’ve
disabled bi-directional support and advanced printing options.

Have you completely disabled the firewall on the client and tested? This will
ensure that all communication can flow back and forth. The TCP/IP Port Monitor
typically polls the printer using SNMP. Also check the community strings on the
drivers to ensure they match the printers. If the clients have the SNMP feature
installed, make sure it has a matching community string. If everything is
default, it will use the “public” community string.

Also, maybe the newer 64-bit clients have a newer version of the driver and
there is a compatibility issue with the client mapping.

To me it sounds like the printers buffer (memory) may be filling up, but the
communication is not working, due to firewall, SNMP, routing, etc.

There’s also tons of client side printing hotfixes to assess. I assume we’re
talking about Windows 7 SP1 64-bit here? Do they have KB2775511 installed?

I really have no idea where your problem lies, but this may give you some other

Subject: [THIN] Re: offline printers in session

I have been assembling a list of the printers that routinely go into offline
mode on the server.
So far I have the following printers:

HP LaserJet pro 400M401n

Canon MF 8280C UFRII

HP LaserJet P3011/P3015

Brother HL-2230

HP LaserJet P2055

HP Color LaserJet P2605

HP LaserJet 600 m601

HP LaserJet P3011/P3015

Brother HL-2240

In testing I have setup a dedicated server and been Loading teh actual drivers
for those printers on the server and re-directing users to that server only to
test if the drivers are stable, and if there is an improvement. FOr the most
part I haven ot seen ay changes. After a few print jobs, the printer goes
"Offline" on the server and print jobs pile up never being spooled to the
client side. I have turned off Bi-directional support and Advanced printing
options when I can but Again I have not noticed a difference. This issue has
me completely stumped. There has to be an underlying cause, but I have been
unable to find it and am not sure where to look either right now.

I have come across more users that experience this same issue and they are
printing wit the HP laserJet P2035. However I have a large customer base and
this issue seems fairly isolated so I am not sure if being on a 64bit machine
is the only criteria. While it seems top ONLY be happening on 64 bit machines
I am wondering if there is an additional component that I have not found yet.

I have done that as well as turn off "bi-directional support" as i have seen
that help as well.
It has become quite frustrating. The primary printer that this started with
was a Canon with the UFR II drivers.

Try turning off "Enable advanced printing features" in the desktop printer
preferences. I've found that tends to fix some of the issues.

I have run across an odd situation. I believe I have posted on this before,
but have come up with more information about it.

I have several clients that will print from within their session to the client
mapped printers and then the printer will go "Offline" on the server. On the
client machine the printer is fine, but within their session the printer shows
as offline and print jobs queue up. As soon as the log out and back in they
can print again. I have been told that it only happens if they "print a lot"
but I have not been able to find a threshold for "lot of printing." These
clients are using a variety of printers from HP laserJets to Canon UFRII
printers. They had no issues till they upgraded their machines to 64bit
machines. At one location the users that are running 64bit machines have this
issue, but the one person with a 32 bit machine have no problem. They are
running version 13 of the Web client on the client side, but I have in the
course of trouble-shooting tried everything from version 10.2 to the latest
receiver version and saw no difference. Is there any idea why this would start
occurring after the update to a 64 bit OS on the client side? Additionally in
some cases the users have the Universal driver and in some they are mapped to a
LaserJet 4 driver and there is no difference.

Thank you
