Printing operation
The time chart for the spacing and printing, line feed operations are as shown below.
The spacing, printing and line feed operations are controlled by the MPU. The MPU also controls
the entire timing of these operations.
When starting the printing operation, the MPU specifies the distance moved, print start position,
printing speed, etc. to the LSI, and activates the spacing motor. The MPU, when the carriage
arrives at the print position specified, activates the printer to start printing, and when printing
terminates, the MPU activates the line feed motor for line feed operation. During the line feed
operation, the MPU causes the carriage to decelerate. Upon termination of line feed operation, the
spacing operation is performed.
