HELP - Why does my Windows XP-Internet Explorer print Blank pages?

Only does it on internet pages. Word, Excel & others print fine.

Problem is when doing this wirelessly...works fine when wired

Had same problem on another Laptop in my same house...& downloaded HP Web Smart print & it works fine...BUT tried same thing on this 2nd PC...no luck.

Also tried going to Firefox...It printed page 2 of 3....but others were blank.

Have searched the net for hours. I'm sure someone on here will have a solution. Thanks in advance for the help.
