hi,
i'll keep it in the forum if thats ok so others can benefit.
does the text display correctly? if it looks ok in PS then odds are good its something in your printer setup. If it looks bad in PS try turning on Anti Aliasing.
You can also set (in PS7 at least) whether or not to shunt the Vector data direct to the printer. This can be found on the print with preview screen (see attached for more info)
Hope this helps
Icy
