My HP laserjet 4l was working great without any problems. Recently I got a new ISP and as a result go a new Modem and Router.I connected my computer to the new ISP. The HP4l started giving "HP4L printer in error state". I reinstalled the printer on the desktop with the same result.I even installed it on my Laptop with the same message. When I press the button on the printer,it prints the test page. I even bought a new printer cable to make sure that nothing was wrong with it but with the same results.
Any recommendations/help will be appreciated.
