Cannot print documents from Acrobat

HELP - I can no longer print a pdf document. I'm running Acrobat Pro X, it worked fine for about a year, then suddenly I wasn't able to print out any documents from the program. I click 'print' from the File menu and the print dialog opens as usual, but once I select 'PRINT' from that window and the window closes, nothing happens. I've had to send it to co-workers over the network to ask them to print it for me. The file doesn't appear in the cue for my printer. Nothing - it disappears. Is this a driver problem, and if so, how do I fix it? (BTW - The inkjet printer is hooked up to my computer only, and I have no trouble printing from every other program installed on my computer. ONLY ACROBAT.) I've searched the internet for a solution, but could only find answers addressing problems with 'Print as PDF', not ACTUAL printing. Please help!
