Hi, everytime I install my printer, it works fine until I shut down & start up again, in which case there are no printers installed - every time!

Puter specs:

Intel(R)
Celeron(R) CPU 2.00GHz
2.00GHz, 480MB of RAM

Running: Windows XP SP2

The printer I keep installing is HP Photosmart 7550. I have installed the latest driver from here: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ps-10034-2&lc=en&cc=us&dlc=en&product=72891&os=228&lang=en.

I have removed all printers & printer drivers before reinstalling, following the steps on this page: http://members.shaw.ca/bsanders/CleanPrinterDrivers.htm, to no avail.

I keep my computer clean - I regularly RUN Panda Antivirus; SuperAntiSpyware; AdAware; Malwarebyte's & CCleaner.

I'm hoping someone will understand the problem & know the fix because I am at a loss here & really need to print invoices & packing slips for my business.

Not sure if this is noteworthy but I don't know if this is a new problem or not as I've never had a printer installed before.

Thanks in advance!
~BrendaIs that computer have any software that can PREVENT any changes being made?like...Norton GoBack?or any pc recovery card?Not that I can think of. It's got the Panda Antivirus, a handful of anti-spy/adware programs and the rest are web design programs, i.e. the Macromedia suite, Photoshop, etc.Are you member of the Admin group on the MACHINE?
