Abstract
This invention relates to a bar code printing method of printing bar codes consisting of bars and spaces having the width of (n+0.5) P by a bar code printer having a line thermal head with a number of heating elements arrayed at a specified pitch P, in which n +l pieces of heating elements on the aforesaid line thermal head are allocated to sections corresponding to bars in a bar code and n pieces of heating elements to sections corresponding to spaces in the bar code (n: a positive integer in both cases) and the heating elements allocated to the aforesaid bars are heated when bar codes are printed.
Claims1
A method of printing bar codes by a bar code printer having a line thermal head with a number of heating elements arrayed at a specified pitch P;
- by allocating n+1 pieces of heating element to sections corresponding to bars in a bar code, and n pieces of heating elements to sections corresponding to spaces in the bar code (n:
- a positive integer in both cases), and selectively heating the heating elements allocated to sections corresponding to the aforesaid bars by means of controlling a quantity of energy to be loaded to the aforesaid thermal line head to print bar codes, each consisting of bars and spaces having the width of (n+0.5) P, by transferring ink on a plastics-based thermal transfer ink ribbon to paper.
