HP LaserJet 2420dn Printer Drivers

The HP 2420dn LaserJet printer is a superb printer with a plethora of features. The first time I printed several color pictures I was amazed at the superb quality of the black and white prints.

This may seem like a small matter, however one of the features of the HP 2420 LaserJet printer that I appreciate very much among all of its features, is to be able to print an article from a website or even my bank statement from the Bank’s website, without the printer cutting of portions of the right side of the article the full length of the article. I have suffered with this printer “indignity” for many years having to resort to printing in the landscape format if I wanted all of the right hand edge to be printed.

All I have to do with the HP 2420 printer is to highlight the article to separate it from the extraneous written materials and advertisements. I then click on Print and check Selection under Page Range. I then Click on Apply and Print. Only the highlighted portion I want to be printed is printed

Compared to the LaserJet III, the 2420dn is a complex printer. I strongly recommend that you print out the Use and Administrators Guide, double sided no less, and have them bound for reference. You will need them.

I chose to connect the printer to the computer via a router by Ethernet cable. Initially the printer arrived improperly configured. By profession I am an engineer with lots of hands on practical experience. Because of the complexity of the printer I did not know what to do no matter how much reading of the manuals I did.

I called HP technical support and was connected to the Canadian Tech support center. The young man, who answered, listened attentively to me and then proceeded to correct the configuration walking me through the many steps. It sure was an eye opener for me how much I could do with the printer and the many steps it took to configure it. I kept careful notes. A new up to date CD with software for the printer was sent out to me in record time. I have no problem doing these rarely needed tasks myself.

As I got more and more familiar with how the printer works, with help from some knowledgeable people at HP printer technical support and reading the manuals, I am able to do these sometimes seemingly complex tasks myself to correct a minor malfunction or perform a configuration. Do not forget that the HP 2420dn is a complex mechanical and electronic machine as are the Laser printers made by other companies. It works very well and I am delighted with it. The HP 2420dn is very reliable.
