Saving Files as PDF's

I am getting my head around advancing my knowledge of computers by doing a night school course on "Creating and Maintaining A Website" at TAFE. With the knowledge that I gain, I am going to operate a Dreamteam website for my local cricket club.
In one section, I want to save Publisher files (four-page update newsletters) as pdf's. The new multi-function unit at work turns the colour print into a black and white document with little spots (that you get from time to time on a copier) across the page, which don't look sensational and the maroon and gold logo turns into a very dark and unrecognisable blob.
What - if it is possible - is the best way to save these files in colour so I can upload them onto the web page ... at least I know how to upload them
