Abstract
A printing apparatus includes a platen, a carriage, a guide member, and a carriage drive. A printing head is mounted on the carriage. The carriage can move in the axial direction of the platen, so that the printing head can print data on a sheet of paper set on the platen. The guide member guides the sheet of paper inserted in the gap between the platen and the guide member, into the gap between the platen and the printing head. The carriage driver moves the carriage to a predetermined position within a region opposing the central portion of the platen when no sheet of paper is detected to be set on the platen.
