ABSTRACT:
Print control apparatus which combines a first in - first out memory for storing received data with a random access memory for feeding data to a movable type printer to eliminate the need for suspension of receiving input characters or the adding of fill characters or time delays during the period when printer action is suspended during execution of control actions, such as paper feed. The apparatus controls the transfer of data from the first in - first out memory to the random access memory by keeping the latter memory continuously replenished with data as the printer executes its printing action and printed characters are erased from the random access memory.
