Abstract

A method is described for processing overstrikes on a QuietWriter* printer. DisplayWrite 3 allows the operator to print lines containing overstruck text. A separate pass is required to print the overstriking characters for such lines. For Class E printers, like the QuietWriter printer, the operator can select up to three print cartridges for printing. Two cartridge slots, "slot A" and "*", are available on the QuietWriter printer. DisplayWrite 3 allows the operator to insert one cartridge in slot A and, alternately, insert two cartridges in slot "*." When several cartridges are requested within the overstruck area, these requests would require the user to continually respond to printer prompts to insert the correct print cartridge.

Overstrike Processing on the Quietwriter Printer

A method is described for processing overstrikes on a QuietWriter* printer. DisplayWrite 3 allows the operator to print lines containing overstruck text. A separate pass is required to print the overstriking characters for such lines. For Class E printers, like the QuietWriter printer, the operator can select up to three print cartridges for printing. Two cartridge slots, "slot A" and "*", are available on the QuietWriter printer. DisplayWrite 3 allows the operator to insert one cartridge in slot A and, alternately, insert two cartridges in slot "*." When several cartridges are requested within the overstruck area, these requests would require the user to continually respond to printer prompts to insert the correct print cartridge. Also, the overstrike character might not reside on all of these requested cartridges, thus causing incorrect characters to be printed. DisplayWrite 3 assumes that the cartridge active at the beginning of the overstruck area contains the overstrike character. This cartridge also defines the pitch of the overstrike character. All cartridge slot changes and cartridge changes are inhibited while overstriking text since these cartridges may or may not contain the overstriking character. However, because each cartridge defines pitch, DisplayWrite 3 records these changes to determine the correct slot and cartridge to access after the current area in the line is overstruck. Each slot change caus...
