A drive mechanism for a transaction printer, comprising:a paper web for printing a receipt thereupon; a cutting mechanism for severing said paper web; bi-directional stepper motor for driving in a first direction said paper web that is printed with receipt information, and for driving in a second direction said cutting mechanism for severing said paper web after said receipt information has been printed upon said paper web; means defining a program for controlling the bi-directional stepper motor, said program controlling said bi-directional stepper motor to move two initial steps to drive the paper web before printing is initiated, in order to eliminate a squeezing together of print dots on a first row of a receipt printout during print start-up; and a one-way clutch disposed intermediate of said cutting mechanism and said bi-directional motor, so that when said bidirectional motor is operative in said first direction, said cutting mechanism is inoperative for severing said paper web.
