I have bought a new laptop and went to connect my printer to it. i put the cd in and got as for as installation when it said i must be the systems administrater to go any further i am logged on to my computer as the administrater but it still would not letme. my new computer is windows 7 and on the cd for the printer which is hp psc 2400 series it says windows 98. me, 2002, and xp does that mean it is not compatible with my laptop.
depending on how old your printer is, it wont work with windows 7 because it dosnt have compatible hardware. 99.9% of older printers wont work with windows 7. I had a simular problem. You are best to go out and buy a new printer, as all new printers will have the right hardware in them... saves mucking around
