I had a similar problem with an HP printer: (this is an exerpt from HP tech support.)
The issue seems with the software conflict between the HP PhotoSmart
8250 printer software drivers and Net Framework.
To isolate the issue with the HP PhotoSmart 8250 printer, I suggest you
to follow the steps below in the weblink and get back to us with the
result.
MSXML 4.0 Service Pack 2 (Microsoft XML Core Services):
http://www.microsoft.com/downloads/d...DisplayLang=en
NOTE: Clicking the link may give an error indicating it is
invalid. If this occurs, copy the portion of the address
on the remaining line(s) and paste it at the end of the
address showing in your browser until the complete address
is displayed in the Address box.
Once you access the web link and you scroll down to the bottom of the
page, you will find an option of "Files In This Download". Under that
you have five files.
Download all the five files and install only the first file. That first
file will be msxml.msi
After downloading all these files, double-click msxml.msi file for the
installation to start. After updating MSXML files, restart the system
and then install the software from the installation CD. Additionally,
please to cancel the auto-installation wizard and then Browse the CD and
execute the setup file.
Please perform the above instructions and get back to us with results if
the issue persists. We shall be glad in assisting you further with it.
Sincerely,
Anthony
