PRINCIPLES OF OPERATION

2.2.10.2 Data Flow

Data flow is shown in the main routine (Figure 2-63) and the printing routine (Figure 2-64). The main routine
analyzes commands, develops data into image data, and controls interruption (prohibition, permission, opera-
tion). Interruption includes data input from the host computer, paper-feed operation, printing output, and the
refresh operation.
