ABSTRACT:
A paper feeding controlling method for a printer in which a record paper is first fed in a feeding direction until a leading end portion of the record paper reaches a recording position. In this position, the record paper will be printed for a first print line and then line spaced to allow subsequent printing for a next print line. When the end of the record paper advances farther than a paper bail roller after printing for several lines involving line spacing operations in this manner, the record paper is now fed reversely by a predetermined distance until the leading end of the record paper comes to a position forwardly of the paper bail roller in the feeding direction. Then, the paper bail roller is moved away from the platen, and the record paper is advanced by the predetermined distance with or without an addition of one line space distance. Finally, the paper bail roller is moved toward the platen until the record paper is held between the platen and the paper bail roller, and printing will be resumed.
