Four dedicated inputs control printer functions. Designed to interface to open-
collector outputs, these inputs require no external pull-ups, while blocking diodes
allow the use of totem pole outputs from +4.5 VDC to + 26 VDC. Optical isolators
provide galvanic isolation. Two print control interface circuit examples are given
below.
