Abstract

PURPOSE:To prevent occurrence of a curl, etc., by waiting an end of a sheet at a cutter at the time of non-printing, and automatically retreating the sheet up to a home position of printing in the case of starting the printing. CONSTITUTION:Before printing, a sheet in a standly state that an end of a residual sheet is placed at a position of a guide 31 immediately before a cutting edge of a cutter in a state cut at a previous time. In the case of starting printing, a print controller drives a stepping motor in response to a stored program, and drives to retreat the sheet S to the home position for printing. When the printing is started from this state and one page is printed, the sheet is driven forward, and when a trailing end of the printed sheet coincides with a cut position, feeding of the sheet is stopped, and cut for one page. At this stage, each printing is judged by the program, and when next page is subsequently printed, the sheet is retreated to the home position.

2. Description of the Related Art In a printer equipped with a paper cutting cutter, the paper is normally fed forward every time one page is printed, and the feeding is stopped when the end of the printed one page reaches the cutting position. The cutter is operated, the paper is then retracted until the leading edge of the remaining paper reaches the printing position, and the paper is made to stand by in preparation for the next printing. This standby position (see FIG. 3B) is the home position,
It is treated as the origin of the paper position.
