changing driver results in 'printer driver is not installed' error on server 2008

Hi,

I'm facing this strange problem.

First I installed a two drivers:
HP Color Inkjet cp1700 and HP color Laserjet 2550 PS.
Then I installed a printer, using an existing driver (one of the two above).
So far no problems.
But when I change the driver to the other driver installed on the server (in the advanced tab of the printer properties) I get this strange error:
"The 'HP color inkjet cp1700' printer driver is not installed on this computer. Some printer properties will not be accessible unless you install the printer driver. Do you want to install the driver now?" Yes/No
No matter what you choose, from now on this message keeps poping up when you enter printer properties page.

Both the drivers are default drivers, installed with server 2008 (not downloaded from the HP website). A lot of other HP drivers (on server 2008 DVD) have the same problem, but not all of them.

I tested this on server 2008 standard and enterprise edition, x86 and x64. All the same problem.
I tried to use the 'standard' way to add/manage printers by control panel > printers. And I used Printer Management. All the same.
Sharing the printer or not, does not make any difference.

Are there people having the same problem? Or maybe already a way to solve this?

Thanks,
Dirk
