The Apple Silentype is Apple Inc.'s first printer, announced in 1979 and released in March 1980 US$599, shortly after the Apple II Plus. The Silentype's firmware was written by Andy Hertzfeld, who later worked on the Apple Macintosh. The Silentype is a thermal printer, which uses a special paper and provides 80 column output. It was also compatible with the Apple III. The Silentype printer needs its own specially designed interface card, or an Apple III with the built in Silentype port. It is mechanically identical to Trendcom's Model 200, except for the Apple logo in the lower left corner of the front cover, but the internal digital board was completely redesigned by Apple, removing the relatively expensive microprocessor and memory chips, relying on software in the Apple II instead. It was succeeded by the Apple Dot Matrix Printer, released in October 1982 for US$699.
The Silentype was inexpensive compared to other printers of the day (most of which cost over $1,000), although the printing looked very much like that produced by a dot-matrix printer. The Trendcom Model 100 printed 40 characters per line on paper that was about 4½ inches wide. The Model 200 could print 80 columns per line on paper 8½ inches wide. Compared to the first printer offered by Radio Shack for their TRS-80 computer (which was also a thermal printer but used a silver thermal paper), the Trendcom printers were superior.
The Silentype's many dramatic advantages over other printers at the time, including silent operation, very small size, print speed and reliability, were especially well suited for its use in the nascent point of sale and hospitality industries. The Silentype was the first printer to be used in any restaurant as a point of sale remote requisition printer to speed service. The broadening use of printers in the hospitality industry subsequently played a key role in the advancement of efficiency throughout the hospitality industry worldwide.[original research?] The typical point of sale hospitality printer in use today, thirty years later, is a thermal printer that still mimics the way the Silentype was used when it was introduced in 1980.
