DRIVE METHOD
5.1 THERMAL HEAD DRIVE TIMING
Input of print data
Input of DAT and CLK transfer the print data to the shift register in the serial input. “High”
means printing and “Low” means no-printing in DAT. DAT data is read in at the rising edge of
the CLK inputs. The transferred line of data is stored in the latch register by turning LATCH to
“Low”.
Input of the head activation pulse
Setting the DST on "High" drives the heat elements of the thermal head. Select the block to be
activated and drive for the time calculated using the formula shown in
"3.6 CONTROLLING
THE HEAD ACTIVATION (DST) PULSE WIDTH"
, then set the DST to "Low".
Figure 5-1
shows the example of timing chart of the thermal head driving.
1:
The print data for next dot line can be transferred immediately after storing the print data into the latch register.
