I use the Pinter Control panel in XP but cannot find the HP3600n printer. When I had a Linksys I was able to add Printer and it was able to find the printer relatively quick.. Now using either Vista Ultimate or Xp Pro with SP2 does not find or pick up the TCP/IP printer. I need to print some important documents but cannot do it after I got this DIR655 DSL Router. I am connected directly [wired] to the Router. Using XP or Vista Ultimately, I was unable to find the printer using wizard or even connecting via TCP/IP. Using Linksys 110, 310+ series had no problem.
