What printers did TI produce for the TI-99/4a?
To my knowledge there are two printers that TI sold in relation to the TI-99/4a; the TI Solid State Thermal Printer and the TI-99/4 Impact Printer. The TI Thermal Printer is a small thermal printer that prints on 3.5″ wide thermal paper rolls. It prints an average speed of 30cps and each character is 5×7 matrix. It’s casing matches the silver/black consoles and it is a little bit larger than the Speech Synthesiser. The TI-99/4 Impact printer was OEMed from Epson and is equivalent to an MX-80 printer. It is a 9-pin dot matrix printer that has both a serial and parallel port.
