• Line Spacing
Line spacing is the space between the lines of printed characters (See Figure 1-2).
The printer uses a line thermal print mechanism, therefore, a paper feed step is necessary before
printing characters or bit images. The line feed with printing feeds the paper for height of
characters or bit images. Therefore, a paper feed amount which is smaller than character or bit
image height is ignored. When the printing includes underlines, the printer feeds the paper with the
line spacing added 3 dot-lines to the character height.
Line feeding without printing feeds the paper for specified line feed amount.
• Character Spacing
Character spacing is the space area adding to between each character in the horizontal direction
(See Figure 1-3).
• Line
The word "line" in this manual indicates a line of characters printed on thermal paper.
For example, the sentence "the printer feeds paper 1 line" indicates that the printer feeds paper a
line of characters.
• Dot-Line
The word "dot-line" in this manual indicates an area of 1 dot in the vertical direction of thermal
paper.
For example, the sentence "the printer feeds paper by 1 dot-line" indicates that the printer feeds
paper by the space of 1 dot.
• Fixed Division Drive and Dynamic Division Drive of Thermal Head
In the fixed division drive method, the logical blocks (a group of physical blocks simultaneously
activated) are predetermined. In this method, high quality printing is available because the
physical blocks are always driven in the same order.
In the dynamic division drive method, counts the number of dots in each physical block so that the
