13. What is the first step during upgrade?

Avoiding unintended issues resulting in a change to the shared UNIDRV and postscript files has been an issue.

Updates to these files come unannounced and unplanned through update services, installation of service packs,

.NET framework, or a hot fix from Microsoft that might negatively impact driver upgrades dependent upon

UNIDRV and PSCRIPT version.

Upgrade has several steps that should be followed. To see what version of UNIDRV and PSCRIPT files are on

the system and compare against the version you are about to install, see Versioning of print driver shared files in

Appendix G. If the versions are different, this might increase the scope of testing required for an uneventful

upgrade. For the HP recommended upgrade steps, see Upgrading the HP UPD in chapter 6.

14. Is there a tool or method available to force clients to disconnect their print connection to the print server and re-

establish the connection?

A tool for this function can be found in the HP Printer Administrators Resource Kit (HP PARK). To download the

HP PARK, go to www.hp.com/go/upd and click Download now. Verify your language, and then click your

operating system. Expand Software – Universal Print Driver. To the right of HP Printer Administrator

Resource Kit, click Download. Save the file and then click the folder and click Extract all files.

15. HP UPD displays "HP Universal Printing PDL**" in the Printers folder. How can I make the HP UPD display the

printer model name instead?

A tool for this function can be found in the HP Printer Administrators Resource Kit (HP PARK). To download the

HP PARK, go to www.hp.com/go/upd and click Download now. Verify your language, and then click your

operating system. Expand Software – Universal Print Driver. To the right of HP Printer Administrator

Resource Kit, click Download. Save the file and then click the folder and click Extract all files.

16. Are there thresholds or guidance limiters to scaling the HP UPD on a single print server?

HP UPD does not have a bounded limit to scale of installation. The recommendation of how many queues to

install on a single server is entirely site dependent. Questions such as this are best answered by IT administrator

policy placing criteria on status and monitoring, server disk/CPU/network IO utilization rates, print job throughput,

peak load times, etc. Some very well managed sites with resources can run 1000 print queues on the right server

with redundancy and high availability requirements satisfied.

17. What does WHQL look at when it breaks: file byte size, date of file, etc?

When the driver is signed, part of the process is creating a hash of the contents of all the files that are part of the

driver, including the .cfg or .cf_ file. If you alter even one bit in any file, the hash breaks.

18. Why am I unable to delete the HP UPD print driver?

The print spooler must be stopped to release the HP UPD print driver. Perform the following on the command line:

C:\NET STOP SPOOLER && NET START SPOOLER.

19. How can I select the version specific driver in Windows 2008 R2 and Windows 7 when using INSTALL.EXE and

creating a new port during the installation?

When you use INSTALL.EXE to install HP UPD in traditional mode, you can select Add a local printer. When

selected, you can create a new port using the Standard TCP/IP Port, you can select Query the printer and

automatically select the driver to use in the screen titled Type the printer hostname or IP address. By

default this query option is enabled. In order to see the driver specific version you have to disable the query

option.
