At least our 2230, 2260 and 2290 UC only and 96 character set printers didn't. Got the same speed regardless of the columns on those Data Products printers. They were drum, as were the Data Printers, but apparently the hammer logic vs. the line feed was not coupled as far a speeding up with fewer columns. Thanks jim
