Abstract
An impact printer is capable of printing at either ten characters per inch or fifteen characters per inch by changing the type character carrying member. The print hammers are spaced at the same distance apart as are the type characters on the carrying member or band and the hammers are displaced from a home position by one space for printing the fifteen characters per inch at a higher speed than when printing at ten characters per inch. The hammers are time shared and are caused to be moved or shifted a precise distance of 4 increments of 1/30 inch each for a standard pitch band at ten characters per inch or a precise distance of 2 increments of 1/30 inch each for a compressed pitch band at fifteen characters per inch.
