Question : Windows 7 Printing

Randomly receive "Operation could not be completed (error 0x00000005). Access is denied." when trying to add some HP printers from a Windows Server 2003 print server.  All Windows XP clients are able to add the printers just fine.  Am basically adding using \\printserver\printer to add the devices.

By default vista and win7 allow only administrator to install print drivers, i think you are trying to install through local user ?
If yes , follow below steps to do manually

Login as local user --> control pannel--> double click printers--> then run as administrator (Alt+right clik choose run as admin) --> Add local printer--> create new port , for type choose local port -->enter port name (adress :- //ip adress/sharename of printer ) --> next --> finish
