WRIGHT (Manuscript received June 6, 1978) An inexpensive, reliable, impact pin printer adjunct has been designed to increase the range of applications for the Transaction II telephone and Transaction III terminal. The printer will accommodate a wide variety of forms due to its slip printer format and its ribbon inking mechanism. The character set includes the upper and lower case alphabets, numerics, and 25 punctuation marks. These can be printed at densities of 30, 40, or 50 characters per four-inch line at a rate of approximately 1.0 line per second.
