As a user of linux I take it for granted that I can create PDF documents. It is not as straight forward for Window OS users.
I have been asked in the past to recommend an application for creating PDF documents. The application I use in Windows is CutePDF which installs a printer in Windows.
It can be downloaded from http://www.cutepdf.com/Products/CutePDF/writer.asp
You need to install the PS2PDF converter first, the link for this software is on the page.
