Have an HP Laserjet 4 connected to the parallel port of a Dell PC. When I turn on the LaserJet, it shows "22 error" and the Form Feed light is on. After a few seconds the green ready light comes on, and the On Line light comes on (steady), and the Form Feed light is on. The same thing occurs if the printer is directly connected to the parallel port, or is routed through the external Zip drive. By fiddling around with the reset, and a number of combinations, I can print a page correctly from time to time, so there is a connection to the data coming from the computer. ??? Thanks for your assistance. I heard from you from PC World. The only option I saw below was "Banner Exchange" or "Search Engine".
