Abstract
In forming a desired print gap between a sheet of paper fed on a platen and a print head by driving a moving mechanism for changing a space between the platen and the print head, a condition where the space between the platen and the print head becomes smaller than a predetermined value is detected, and in this case the space between the platen and the print head is increased by a driving portion for driving the moving mechanism. Accordingly, when a thin paper is used as the sheet of paper, cutting, wrinkling, etc. of the thin paper can be prevented.
