XP Pro SP3
I have a HP 6L printer that has worked for years.
About 6 months ago I bought a new computer with no printer port and got a usb to printer post adapter. It has worked well since.
Today, I tried to print a document and it would not work.
I invoked the printer troubleshooter and followed ALL instructions, numerous times. This involved re-booting both the comp. and the printer numerous times.
As I re-booted, the printer keeps booting up as being "off-line". One message said that there may be a problem with my printer port. I followed the instructions to install the port manually. I received the message that the port was installed. Still no difference.
The printer self-test works.
Can anyone advise me?
EDIT, July 29.
Well after many attempts at reinstalling the printer, I ran Microsoft Security Essentials on deep scan. I have been using Malwarebytes for thorough scans. MSE for a few dangerous files and removed them. This seems to have solved the problem; I'm again connected. I also had another problem with dropped WIFI and suddenly that seems to be working properly. Cross reference: http://superuser.com/posts/132753/edit
