PRINT DRIVE METHOD
5.1 MOTOR AND THERMAL HEAD DRIVE METHOD
The motor and the thermal head must be driven at the same time for printing.
The printer uses the thermal head with heat elements which size is a half-dot size of the feed direction. One
dot is, therefore, composed of two of the half dots. The motor feeds the thermal paper for one dot line with
four steps. In order to print one dot line, feed the thermal paper for four steps and activate the thermal head
in every two step.
The following describes the drive method as an example of the LTPD245D.
Figure 5-1 shows a timing chart for driving using six division printing.
Figure 5-2 shows a timing chart for driving using one division printing.
