Abstract

PURPOSE:To improve an accumulated line feed accuracy by a method wherein a line feed execution amount to be executed when a cutform is fed is added to an integrated line feed execution amount, and when the added value is more than a predetermined amount, the paper is fed by an amount obtained by correcting the line feed execution amount by a predetermined correction amount. CONSTITUTION:When a cutform is inserted to a cutform insertion mount 30, the paper is fed between a platen 12 and a printing head 13 by paper suction rollers 15 and paper feed rollers 16. In the cutform feeding, a line feed execution amount to be executed at the time of line feed is added to an integrated line feed execution amount. When the added value is less than a predetermined value, the paper is fed by the line feed execution amount, and the added value is used as a next integrated line feed execution amount. When the added value is more than the predetermined value, the paper is fed by an amount obtained by correcting the line feed execution amount by a predetermined correction amount, the predetermined amount is subtracted from the added value, and the result is used as a next integrated line feed execution amount. In this manner, in the cutform feeding, a paper feed amount is corrected by the predetermined correction amount every time when a line feed amount reaches the predetermined amount.

However, the cut sheet gets caught in the paper feed roller,
Paper is fed only by so-called friction feeding. Therefore, if the paper feed roller is in the state of overfeeding or underfeeding as described above, the cut sheet will continue to be overfeeded or underfeeded. Therefore, when printing on cut sheets, the cumulative line feed accuracy is poor, and as line feeds are repeated, the printing position gradually shifts in the line direction.
