HP Laserjet 600 M602 - Que backing up - printing characters and symbols. This is an intermittent issue. usually happens on a multipage page print job. Is happening on two printers. both are attached direct to the pcs. I have updated the print drivers and installed the entire software suite to each. still having problems. Below is a Jpeg and also full attachment.
