Abstract
In a method for operating a serial dot matrix printer having a print head that is reciprocated along a first direction and stopped for performing bi-directional printing on a medium that is moved in a second direction orthogonal to the first direction, correction amounts for correcting the bi-directional printing alignment are stored in a memory device. The desire correction amount is then selected and stored in a battery-backed-up memory. The bi-directional printing then is performed using the desired correction amount stored in the battery-backed-up memory.
Claims4
A method for operating a serial dot matrix printer having a print head that is reciprocated along a first direction and stopped for performing bi-directional printing on a medium that is moved in a second direction orthogonal to said first direction, said method comprising the steps of:
- storing in a memory device a set of correction amounts for correcting bi-directional printing alignment;
- reading and successively printing said correction amounts;
- manipulating a key, when a desired correction amount is printed, to input a command signal for registering said desired correction amount in a battery-backed-up memory;
- and
- performing said bi-directional printing using said desired correction amount registered in said battery-backed-up memory.
