wants to save prn file. (Adobe print command shows correct, default printer name.) Printer works fine with other applications and used to print pdf files from Reader X even 2 weeks ago. Windows 7 x64 with MS Security Essentials - all systems up to date, no system changes (hard or soft) other than regular security and version updates.
Ran Adobe Repair and rebooted - print command showing attached printer still asks where to save the prn file instead of sending job to turned on printer which works fine just before and just after Adobe fails to use it. Will install older version of Reader, Adobe offers v9.5 if no one has a better solution since I am clueless.
