One of the things I miss in Windows is the “it just works” print to PDF feature in Linux. If you’re willing to do some work, however, you can set up something similar.
The following is by no means an exhaustive list; it’s just those offerings I’ve had a chance to look at.
CC PDF Converter: Open source. Optionally stamps the generated PDF with the license of your choice. On one installation, first use took several minutes to generate a PDF, causing the operating system to think the application sending the print job had crashed. Subsequent use is easy and quick. My current choice.
CutePDF Writer: Proprietary; available at no cost.
PDFCreator: Open source, but by default the installer adds additional proprietary software that many scanners classify as malware. Full featured and overkill for the casual user. Expect to spend some time reading the documentation, configuring, and instructing the end user.
Superuser: Recommendation for a simple no-frills Windows PDF printer driver
