Can't finish printing first page of wireless print

I print via NetGear RangeMax WPN824 v2 router and D-Link DPR-1260 print server to HP OfficeJet 5610 All-in-one.

The last time I successfully did so was June 4, 2008. Before then, for a year, I had no problems. Since then, every print I’ve tried hangs up just as the printer is a line or two from finishing a first page.

I have a Toshiba Satellite A-205 (laptop) with Vista Ultimate. I have tried to re-install the D-Link many times.

My wife continues to print problem-free from an older Lenovo XP machine, via the same set-up.

The only things that had changed on my machine since my June 4, 2008 successful print are a Windows Defender Definition Update and my renewal of Trend Micro’s Anti-Virus and Webroot’s Anti-Spy. I of course cannot remove the Defender Definition Update, but at TrenMicro’s & Webroot’s suggestions, I have disabled my Anti-Spy and Anti-Virus for attempts of D-Link re-install. No success!

I have also tried the re-install with and without the WinVista Service Pack 1.

I would very much like to restore my wireless printing from the WinVista machine with as little cost as possible.
