If tht URL does not work for you, copy/paste it into your browser or go
to www.hp.com / Software and downloads / laserjet 2600n and then VISTA.

While you are there I would download the firmware fix and anything else
that relates to your printer and VISTA.

The important thing will be to unplug the USB cable from the printer to
the PC (if that is what you are using and not the network option)
uninstall the printer and install the new HP software without
connecting the printer until either the installation software tells you
to or you reach Finish. Then when you connect the printer, VISTA should
install it with the HP software instead of what is in with VISTA.

But bring us uptodate first including how your printer is connected to
the VISTA machine.
