A line printer which comprises a standard type-belt (1) having a plurality of character sets (2), clock (CL) marks for individual characters, and home position (HP) marks for each character set. Further, the line printer comprises a belt image memory (13') for storing the character codes of the characters of the type-belt (1). Flag bits are inserted at positions of the belt image memory (13') corresponding to the reference marks of the character sets (2). Further, the output (HP-D) of the belt image memory (13') is compared with the output (HP) of the type-belt (1) to perform a belt synchronous check. |
