This problem just started. I have a new computer with two printer ports. One is hooked to a line printer and the other to a HP Laserjet 5p. When I print to the laserjet it reboots the computer. Not every time I try to print. About 40% of the time. It has recently started doing it when I print to the line printer as well. These printers have been on this computer for months with out any trouble. Any ideas on what I should do to fix the problem.
