I just purchased 3 HP 602 printers for the office. We are having issues with gibberish printing on old documents saved as a word .doc file. Any help? We installed the print driver on the CD that came with the printers, but I think we are going to try to install the pcl5e print driver to see if this helps. We have additional issues of the printer not obeying the tray commands for the documents as well. Any other suggestions? Thank you!
