Using Windows 7 64 bit. The printer is an HP Laser 1200. The 64 bit driver for the printer would not work, so I switched to the hp 2200 64 bit driver and the customer was able to print out of his CAD program and Excel.
However Adobe Reader is a different matter. He got the message "print driver for the 32 bit app has stopped working" and printed out 3 blank pages. Then he tried to print again, didn't get the message, and didn't get the blank paper. In fact, he didn't get anything.
Of course, there is no information on the HP website. Any ideas on what could be the problem?
