Hi All
Im having real trouble with iPrint an our HP Printers 3005's and 2420's

basically the drivers are uploaded and the printer can be installed from http://server/ipp this no problems but when i go to print i get

'An unknown error occurred while printing.' when i right click propities the printer i get

'The 'HP LaserJet P3005 PCL 6' 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?

i choose yes and see that the machine has the driver so i choose it get the successfull message but if i right click propities i get the message again

i have tries running IE and Mozilla as administrator but it has made no difference

any help would be great :-D
thanks in advance
