ABSTRACT:
The printer of the present invention prevents loss of print data due to print operation malfunction after the completion of the initialization of print head 3 by detecting error conditions related to the motion of the print head during the initialization of the print head. In the initialization process of print head 3, print head 3 is moved until it is detected by reference position detector 16 located at the left edge of the print area of the printer; after completion of the initial-position detection for print head 3, print head 3 is moved over the entire print area to rightmost move position 37. By moving print head 3 as described above and by checking whether or not the print head has moved correctly, it is possible to detect any error conditions relating to the motion of print head 3.
