PDF usability and best practices?

I have a friend in the City who has been dealing with a lot of printer issues recently.  The print server has 32-bit drivers on it, and none-of the computers with Windows 7-64 bit can print to the print server, but the Windows 7-32 bit can.

PDF related but off topic.

Our library has 10 public computers using Win7.
We replaced our previous copier/printer a while back.

The problem as I understand it is that all but one computer cannot print PDFs.

It time consuming to switch patrons around and or use staff level machines to print PDFs.

Could this be:
1) A problem with the new printer copier?
2) A problem with the PDF files themselves?
3) Could the OS be partially responsible?

A key consideration is whether the PDF is "linearized". If it is, then the
browser does not need to download the entire PDF before some of it (the
first page) can be viewed.

Other factors to consider:

* Overall file size (as mentioned by someone else)
* Number and type of embedded fonts
* Whether it's "searchable". When pages of text are scanned, each is an
image. When it has had OCR done on it, it becomes searchable (and could
also be read aloud by screen reader software).
