Dot Matrix?
...what's the resolution of your Laser Printer?? 300...600DPI? Sounds like a "matrix of dots" to me!! I know what you mean though, my mom was a payroll book keeper and I used to dread that day that she had to print pay checks...on 3 copy NCR paper...3 impact printers in a closet they built in her office, tractor feed jumping a line at a time, and even the double glazed sliding patio door couldn't keep the grinding whine of the 24 pin print heads from filling that end of the building. So let's take inventory here...how many technologies did I mention which have gone the way of the buggy whip? Hehehehe
