Abstract

PURPOSE:To control a printing position vertically, by a method wherein a synchronous skip part outputs a paper-feeding skip signal to a printing control part when a travel amount set by an operation panel increases beyond a control range to control a printing position. CONSTITUTION:In a video signal generation part 10 of a printing controller 9, data outputted from a host computer 1 is converted to a video signal to be outputted to a printer 15. At this time, a vertical printing position set by an operation panel 12 is outputted to a video signal control part 13 and a vertical synchronous skip part 14. Then, with the start of a paper-feeding in the printer 15 according to the output of a printing control part 11, the video signal is outputted from the video signal generation part 10 to the printer 15 under the control by the video signal control part 13, and a printing is carried out. If the vertical printing position set by the operation panel 12 is beyond a paper- feeding control range, the printing control part 11 skips the paper-feeding under the control by the vertical synchronous skip part 14, whereby the video signal from the video signal generation part 10 is outputted to the printer 15 earlier by the skipped amount in paper-feeding to be printed.
