In using a QUIETWRITER printer connected to a personal computer (PC) so that the keyboard of the PC functions as a typewriter keyboard with the printer having a sheet of paper therein to print as the keys of the keyboard are depressed, the carrier of the printer is moved in response to each depression of the spacebar without modifying the printer in which a space accumulation algorithm controls when the carrier of the printer moves during use of the printer under control of the PC memory rather than as a typewriter. To save ribbon, the QUIETWRITER printer does not move when a space is sent to it from the PC memory. Instead, the printer, which has a space accumulation algorithm, accumulates spaces and turns them into tab operations, which do not use ribbon, when more than a predetermined number of spaces is received in a row.
