Issues when using HP printers in Citrix environments

Resolved issues

Citrix Universal Print Server – Print jobs hang under high print load conditions.

It has been reported that the Citrix Universal Print Server process (UPServer.exe) will hang or crash under heavy print load

conditions when using the HP Universal Print Driver. Restarting the UPServer.exe process will free up the print jobs.

Solution: This issue is fixed in the HP UPD 6.2.x release,

Job storage not working as expected when printing from a XenApp published application

A job will not be stored in-device when printing from a published application in XenApp if the application is published as

Allow anonymous users. This happens because UPD job storage requires the user ID to store the job; however, in this case,

the application is run as an anonymous user on the XenApp server.

Auto-creation performance in Citrix

In general, the time it takes to auto-create a printer using the HP UPD or a model specific HP print driver version

60.xxx.xxx.xxx or 61.xxx.xx.xxx is 2 – 10 seconds, depending upon the performance and load of the print spooler and other

processes on the Citrix server. This is due to the time taken to initialize the HP UPD or model specific print driver.

When using the Citrix StressPrinters tool to test the HP UPD, selecting the default LPT1: port from the tool provides install

times that are not accurate. The HP UPD attempts to communicate with the printer over the LPT1: port and times out after a

long period of time. To achieve a true simulation of the HP UPD, run StressPrinters from a Citrix server and select a Citrix

redirected port that is connected to a live network printer.

HKCU\Software\Hewlett-Packard registry hive increases in size in Citrix

Print driver versions 61.071.xxx.xx fail to clean up registry data written to the HKEY_CURRENT_USER\Software\Hewlett-

Packard registry hive. Keys under this hive will grow over time – a new registry key is created each time a user logs on to a

Citrix server for each printer auto-created. An example of such a key is HKEY_CURRENT_USER\Software\Hewlett-

Packard\165b5934-15c4-4a84-c392-d044915211da where 165b5934-15c4-4a84-c392-d044915211da is a globally

unique identifier (GUID). HPBIDIInfo and HPCUSTOMForms are keys in the GUID hive.

Newer versions of the print driver, such as version 61.081.xxx.xx or the latest HP UPD, have a fix for this issue.

Memory issues cause problems with spooler, auto-creation, and server performance

The following components may cause issues:

 hpbmini.dll – Memory leaks and memory corruption are possible with the 1.0.0.18 (or older) dll, which will not cause a

spooler crash but may degrade server performance. This issue occurs with 60.x.x.x and 4.x.x.x. print drivers containing

hpbmini.dll version 1.0.0.18 or older. Version 1.0.0.19 and newer has the fix.

Version 4.x.x.x print drivers have an issue unloading hpbmini.dll, which will probably cause a spooler crash when the

server has a heavy load of connected users.

 hpcdmc32.dll – Memory leaks are possible with the 1.0.2.30 (or older) dll, which will not cause a spooler crash but may

cause performance degradation. This issue occurs with 60.x.x.x and 4.x.x.x print drivers containing hpcdmc32.dll

version 1.0.2.30 or older. UPD version 5.7.0 and later has the fix.

Other symptoms caused by the above components include failed auto-creation of printers and auto-created client

printers not being deleted when users log off.
