Dell 1600n Wireless Printer Connection?

I had a Dell MFP1600n laser printer given to me a while back (Praise the Lord) & it came at the right time as I was destitute then & couldn't afford cartridges for a Canon I960.Here's the rub.There was no problem connecting & using the printer with a wired connection to a Linksys WRT54GS & a wired XP Desktop & a wireless XP Desktop (both older 86X systems).Though the 64 bit, wireless, Windows 7 laptop connected through the same router to the internet. As usual, it would not & still does not "see the XP machines". It also would not, through multiple configurations, connect to this printer.At first I tried to update the driver, but Dell only had XP 32 bit available. After hours & days of wasted time with "Add printer", I resorted to using a flash drive for the few times I needed to print something from this infernal Windows 7 machine.

I finally wondered if my head was stuck in the "soon to be obsolete, XP mode".'know, this isn't the first time Microsoft has Pi**ed me off & I understand that we are all "beta testing" a product that we have paid several hundred dollars for. I also understand the reason for security, but I don't want to spend 50% or better of my time trying to use an OS that cannot tell ME from a scumbag intruder. There are AV programs for that...As it came installed on my laptop (& of course I received no restore or install disks whatsoever with it), I'm stuck with trying to repair, rather than reformat. Unless I wish to pi** away a bunch more money to Microsoft.
