HP 2605dn Print Drivers User Manual

Avoiding unintended issues resulting in change to UniDrv and postscript has been an issue.
Updates to these files come unannounced and unplanned through update services, installation
of service packs, etc that may negatively impact driver upgrades dependent upon Unidrv and
Pscript version.
Upgrade has several steps that should be followed. Specific to this issue, check Server
Properties, Drivers to see what version of UniDrv and postscript are on the system and
compare against the version you are about to install. If they are different this may increase the
scope of testing required for an uneventful upgrade. Refer to
Install and Uninstall of the HP UPD
on page 23 for HP recommended steps.
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 Administrator´s Resource Kit (PARK)
available for download at
h20338.www2.hp.com/Hpsub/ cache/494717-0-0-225-121.html. Click
the link to the PARK beneath the Universal Print Driver Tools heading.
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 Administrator´s Resource Kit (PARK)
available for download at
h20338.www2.hp.com/Hpsub/ cache/494717-0-0-225-121.html. Click

16. Are there threshholds 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 administrative 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.
20. When I delete a printer that is using the HP UPD print driver, is the standard TCP/IP port also
deleted?
