After step 304, printing enable, start and counted using clock counter.
Step 305, judge that whether the numerical value of sampling clock rolling counters forward be more than or equal to this counting reference value P；If big
In or be equal to, then execution step 306；If being less than, wait this sampling clock rolling counters forward cumulative after execution step again
305.
Step 306, output pulse signal, and this sampling clock is counted with device clearing.
Whether step 307, judge to print and terminate；If being not over, execution step 304.If terminating, flow process stops.
In the present embodiment, for example, assume the pulse interval of encoder input to be counted, between obtaining
Be K=3000 every count value, and assume that encoder input signal is ideal, output needs to do 2 frequencys multiplication, then divide/times
Frequency can be set to 1/2,100/200 or 1000/2000, then using formula (1), and counting reference value P obtaining is 1500.
If the encoder input signal cycle is less than normal compared with theoretical value, can arrange frequency dividing/frequency multiplication is 1000/1998, that
Adopt formula (1), counting reference value P obtaining is 1501.Again assume that frequency dividing/frequency multiplication is set to 1000/1997, then adopt

Row adjustment, can reach a sampling clock cycle, such precision just can meet the requirement of printing precision.
In the same manner, if encoder input signal is bigger than normal compared with theoretical value, can also be by arranging frequency dividing/frequency multiplication so that P is
1499th, 1498,1497 etc., thus also disclosure satisfy that the requirement of printing precision.
In addition, in the case that a frequency dividing times frequency ratio is not integer, such as P=1501 or 1499, then corresponding, is defeated
Enter encoder pulse interval (i.e. gap count value) nor corresponding integer output pulse signal, but the pulse signal of output
To count reference value for strict reference, that is, more than or equal to P, then output pulse signal is laid equal stress on New count；Then continue to count less than P,
The response of the pulse signal of the output pulse signal to input coding device with the continuous real-time update of K and P, can be fully achieved
With follow it is ensured that printing precision.

It is equal to, then execution step 306；If being less than, wait this sampling clock rolling counters forward cumulative after execution step 305 again.
In the present embodiment, because the speed of service of stock is variable, therefore, K is likely to changing always, because
, can there are two kinds of special situations of comparison in this：The first situation, the numerical value of sampling clock rolling counters forward are less than or equal to first
When counting reference value, this first gap count value is updated to the second gap count value, then the numerical value of sampling clock rolling counters forward
Can be compared with the second counting reference value.The number of times that second situation, sampling clock count device stored count has been over
First gap count value, but the first gap count value does not also update, then the numerical value of sampling clock rolling counters forward still can be with
First counting reference value is compared, until first counts reference value renewal.
