Had some bad luck recently. My Canon Ink jet stopped printing,but after removing and reloading it, it works again.
Now my trusty HP4 LaserJet Plus after 15 years stopped printing. It is hard wired connected to a desktop running Windows 7. It worked beautifully for many years and now it won't print. I tried printing from Word, Excel, WordPerfect and Foxit Reader. In all cases the On Line light lighted up the paper was pulled into the machine, all the noises inside sounded as they always have. but not one mark, letter, or symbol was printed. Likewise when I pressed the appropriate menu buttons to print the Test Print, the paper was pulled through but it came out mark free.
Any ideas?
