Hey Tom!
Why not save time & money?
Merv swears by pdfMachine
http://www.cadsoft.com/forum/index.php/topic,6623.0.html & I've found it does everything I want. You can change resolution & compression settings in the print driver on the fly.
For example, an A3 sheet full of text (approx the size of 2 Letter portrait sheets side by side) with coloured title block prints as follows:
Best Quality & 1440dpi yielded a pdf of 6.4MB
Low quality & 96dpi resulted in a pdf of 340KB
I'd use the first file for printing a proposal but the 2nd would be for emailing or upload to a website.
http://www.broadgun.com/ is an Aussie outfit but they price in greenbacks. I'd suggest you try their basic pdfMachine Office. If it does what you want it'll only set you back US$29
Don't ask me why us Aussies pay a premium - currently 29.00 USD = 27.4322 AUD but if I wanted to buy a 2nd licence now they hit me AU$33.35
go figure!
