Claim:
A printer comprising: printing means for printing on a sheet of paper by driving a printing head and a carriage; transporting means for transporting the sheet from an upstream part to a downstream part with respect to said printing head; processing means for applying a process along an imaginary line on the sheet at a fixed position located downstream of said printing head; and control means for controlling said printing means, said transporting means and said processing means such that a sheet transporting operation and a printing execution are alternately performed, and after the sheet movement is stopped upon occasion, said process is carried out, wherein, when the sheet is fed by a predetermined sheet feed amount in order to print successively incoming data, at the instant that an imaginary line on the sheet reaches a processing position, said control means 1) stops the movement of the sheet, 2) causes said processing means to process the sheet along said imaginary line, and 3) causes said printing means to restart printing said successively incoming data without moving back the sheet from the downstream part to the upstream part before printing said successively incoming data.
