Abstract
A drum type bar code line printer of the type has groups of predetermined kinds of bar code printing types which are arranged along the circumference of a printing drum in predetermined rows which are distributed along the axial direction of the drum. In each row, a non-printing (non-impact) area corresponding to the width of a bar code type is essentially formed adjacent to one end in the axial direction of the drum of each bar code type which has a black bar portion extending from said one end of the type through the predetermined modules of the type. The printer of the present invention is thereby free from the generation of so-called ghost images which are undesirably imprinted by adjacent bar code types.
