This printer use a line thermal print mechanism, therefore, a paper feed step is necessary before
printing characters or bit images.
The line feed command 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.
Printing with underline feeds the paper 4 dot lines in addition to the character height.
Line feeding without printing feeds the paper for specified line feed amount.
