Re: HP 2420 sudden prints pages in all black

Most likely to be the toner cartridge is it OK on other programs such as the web explorer? If not change the toner cartridge you can also print out the configuration page by pressing the green tick and then using the up and down arrows select information press green tick to enter then move to "Print Configuration" and select using the green tick. If the page comes out OK then the print cartridge if fine if not try changing it. Also there maybe in the driver you have under printing preferences negative mode make sure that is not checked.

Failing this reinstall the print driver from HP Online if this still doesn't work then change the data cable if still not working then I suggest that the printer formatter board is faulty.

I do hope this helps you and please rate me
Thanks J

Can not print in duplex mode I can not print

Why don't you just print the data on the one side of the page and then simply turn the page over and reinsert it into the paper feeder and then print the next bit of data, therfore you end up with both sides of the page printed without worrying about printer commands that seem to fail.

Laserjet 2420d just keeps printing document repeatedly from XP

check hp for latest driver for your operating system, also check if there is a PCL and PS driver. PS is better for PDF. sometimes an adobe update can cause these issues so if you cannot find a driver update you could roll back adobe to see if that fixes your issue.
