pdfs is wierd 'fings ... and adobe is a wierd 'fing in it's own right.
unless you have specialist needs ... I'd personally bin the adobe reader ... and download the free (and easy) Foxit reader
http://www.foxitsoftware.com/pdf/rd_intro.php
adobe 90MB ... foxit a single stand alone 2MB file ... and I'm still trying to find any difference ... at least with standard day to day documents.
(OK so you have to open files on the web instead of having the viewer integrated with IE - which takes at leas two seconds longer !!)
and if you use PDFs which are protected with exotic plugins ... that won't work ... but otherwise ... no problemo.
you can install allongside adobe ... and use it to see if it prints ok
If you must use adobe ... get the latest version ... uninstall yours, reboot then reinstall the new.
