ABSTRACT:
A printing apparatus and a paper controlling method for a printer in which, upon activating a power source or upon changing over to the on-line mode or upon switching to a high paper feed speed, a paper feed motor is rotated first reversely to draw back paper by an amount a little greater than an amount of a possible slack and then forwardly to advance the paper. Accordingly, paper slack can be cancelled adjacent a print head in preparation for subsequent printing. Accordingly, high quality printing can be attained.
