LP 1 (260-1150/52) Features Faxback Doc. # 5656 The modular constructed Line Printer is a low speed, unidirectional impact printer. The machine is capable of printing 5 x 7 dot matrix characters at densities of 10 to 16.5 characters per inch (cpi) for line lengths up to eight inches. Because of the fixed print head speed, the print rate in- creases as the character density is increased. Print rate varies from 60 characters per second (cps) at 10 cpi to 100 characters per second at 16.5 cpi. Vertical line spacing is six lines per inch. This manual provides installation and operating instructions for the Radio Shack TRS-80 Line Printers (26-1150 and 26-1152). Each Line Printer uses a different paper feed system. The 26-1150 uses a pinch roll paper feed for roll paper and the 26-1152 uses a tractor feed drive for multi-part (fanfold) paper. To use a Line Printer with the TRS-80 microcomputer system, you must have the TRS-80 Expansion Interface (26-1140,26-1141 or 26-1142). You received a telephone type cable (Interface Cable) with your Line Printer. Connect the Interface Cable as instructed. The manual also includes other information useful to the printer operator.
