Unlike the more common dot-matrix or daisy-wheel printers (such as the TRS-80 Line Printer or theDaisy Wheel Printer II), the Quick Printer was an “electrostatic” printer that required special aluminum-coated paper. Radio Shack sold a package of three rolls of the 4.75″ wide “aluminized electrostatic spool paper” (catalog number 26-1405) for $16.95.
The Quick Printer worked by electrically burning away the aluminum coating of the paper. With the aluminum burnt away, the black backing paper underneath was exposed. The printing/burning process created both a very distinctive odor and sparks that were clearly visible when printing in a dark room.
Characters were created using a 5 by 8 matrix at a maximum speed of 150 lines per minute. The output, described as “black-on-silver,” reproduced well on photocopiers.
