Printing problems with a Brother MFC4600

I purchased windows xp and now having problems with
printing on my Brother Multifunction. Either my attempts
take 5 - 15 mins to print or are unsuccessful. I
contacted brother about this and was advised that it is a
problem with xp. Is there a way to fix this? the support
at brother suggested changing my LPT1 port from ECP to
standard (for which I have no idea of how to do), see if
others knows of this problem and how to resolve it or
find if a patch is available. I was unsuccessful in my
attempts to find a patch.
