Printer Error

Does anyone know why when I try and print off the internet I get these two errors?

!An Error has occurred in the script on this page.

Line: 1038
Char: 5
Error: Unspecified error.
Code: 0
URL: res://C:\Windows\system\shdoclc.dll\preview.dlg

Do you want to continue running scripts on this page?

[Yes][No]

Then the other error:

There was an error writing to LPT1: for the printer (HP Deskjet 930C Series): There was a problem printing to the printer due to an unknown system error. Restart Windows and then try printing again.


I've restarted windows and what not, but sill get this error.

Any ideas?
