Windows 2008 Print Services, HP LaserJet Printers and SLOW Printing

If you have moved to Windows 2008 for your Print Server and have encountered slow printing to your HP Laserjets, the issue may be the driver.

According to this support document by HP the issue lies in the HP Bidirectional Channel component - namely hpzbid.dll and hpzbidXX.msi). You can read all about the symptoms/cause there but to make a long story short it appears that this lies with issues where it continually tries to reinstall the .dll and fails.

The solution, according to HP, is NOT to call up and get updated .dlls (they probably will not give them to you) but to use their updated Universal Print Driver (UPD) version 5.0. This changes the .dll to cioum.dll for the bidirectional channel control rather than hpzbid.dll. HP has no intention of updating hpzbid.dll so get used to it.

The symptoms are hard to miss (for example it takes 30 seconds just to view the properties of a printer on a client machine) so this one should not be hard to miss. Just remember to use the 5.0 version of the UPD.

Printers noted by HP:

• Laserjet 4250 series
• Laserjet 4350 series
• Laserjet 9040 series
