My HP LaserJet 1200 was working fine until I decided to change the router to a DLINK DI-713P wireless router. Now, my printer does not show up on the network. I went to the DLINK web site and read about PPA printers. The DLINK website offered no tips on how to correct the issue but only referred you to HP. HP does not offer "free" technical support for this printer any longer. Before I pay for support, I thought I would see if anyone knew of a way to fix this issue. I've tried reinstalling the printer driver using both the IP address and the hardware address. No luck. I'm using Windows 2000, Windows XP and Mac OS 9.2 on this network...I appreciate any suggestions you may be able to offer...
