dot line so that the number does not exceed the specified maximum number of activated dots. The
In dynamic division, in order to avoid unclear printing, at the first step of the motor the thermal head is driven and at the second step the paper is fed.
Also, since the order of the printing blocks and printing speed are changed in each dot line according to the content of the print data, print quality may be lower than that in fixed division. If print quality is regarded as important, printing in fixed division is recommended.
The maximum number of activated dots in the initialisation status is specified using the function switches.
64 through 256 dots can, however, are set using the command for setting the number of dynamic division dots.
When the maximum number of activated dots is 128 dots, and all of the dots are driven, as shown in

2.7.5 Vhead interrupt circuit
This circuit interrupts Vhead to prevent electrolytic corrosion of the thermal head and to enable the detection of the resistance mentioned above.
