I found this during a look for other problem(s). Since it was released on Sept/2009 its fairly new. Also, used for the infamous print queue stoppage problem. That problem is fairly common to USB HP printers and the utility can help resolve this and/or be part of the solution process for other problems. When visiting the HP support website for your model#, find the "Software and Driver" section, locate utility heading and d/l.

The utility is available for most of the HP printers. Enjoy -----Willy
IMHO, Moderator consider this post for a "sticky"?

Under Rel 1.1, the Utility ONLY worked on inkjet printers (example Officejet J4580 A-i-O) - the new release [1.5] now works on other HP printers connected via USB (example Laserjet 1320). [Windows XP Pro environment]
General comment - please, moderators and repliers alike - ALWAYS put a date on your comments. When someone reads them, it is important to know whether the information is current, relatively current, or downright obsolete. I have wasted many hours following someone's advice only to find out that the information is about a product no longer in existence or has it been renamed or the supplier has quit providing the product. Thank you.

Thanks for the link, Willy.
I'm a newbie tech (spelled, there's nobody else here to do it, so I'm stumbling along), and working on/with 2 laptops and a cheap netbook. I do have an OfficeJetJ6480, and your link helped with the Acer Netbook.
HP and Compaq laptops, however, print any document endlessly. All settings say 1 page, and so does the print queue - until I click - then the Page column in print queue jumps to 3x/pages, but actually prints forever and ever. I've uninstalled/re-installed, from disc and from online. Same result on both machines.
I've not seen this reported anywhere.
At least I can print from the Netbook, so that's its function right now. Suggestions welcome.

My Win 7 64bit loses my printer at random times. I tried the Print Diagnostic Utility and it found no problems. AKerans

As you can see, not only the drivers have been totally updated and upgraded, the software of it all has been upgraded/updated as well. Several miscellaneous Updates offered and, 3 utility programs offered also.
This link is only useful for the Photosmart C7250 All-in-One unit. For all other units, a totally different support web-page for them.
Enjoy your 2010 software programs everyone!
