232.1.7 Printing operationThe 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 controlsthe 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 carriagearrives at the print position specified, activates the printer to start printing, and when printingterminates, the MPU activates the line feed motor for line feed operation. During the line feedoperation, the MPU causes the carriage to decelerate. Upon termination of line feed operation, thespacing operation is performed.Figure 2.10SP MotorOperationPrintPrintingAcceler-ationDeceler-ationConstant speedLine FeedLF
