Abstract of the Disclosure: Disclosed is a pen type printing apparatus having a reduced size and weight so as to be suitable for use in combination with a personal computer or the like. The apparatus has a paper feed roller adapted to be driven by a motor. Two short roller shafts are arranged at each axial end of the paper feed roller so as to extend in parallel with the latter. These roller shafts rotatably carry respective pressing rollers of small diameters. The roller shafts are biased toward the paper feed roller to bring the pressing rollers into pressure contact with both axial end portions of the paper feed roller to clamp a printing paper therebetween. A carriage is movable transversely of the printing paper and carries a pen which is projectable selectively. Any desired character, symbol or a chart can be printed on the substantial mid-portion of the printing paper where no pressing roller exists by combination of the shifting of the carriage, feed of the projection of the pen, in accordance with a printing instruction.
