Time in continuously transmit, this threshold time, in actual test find be usually within 10 seconds, so, if wait
Also do not continue to receive print data more than threshold time (such as 10 seconds), be considered as having received a complete print data.
Second, buffering area strategy.Data buffer zone size can be pre-set, when data buffer zone data expire, just
It is considered a complete print data, then one print data of many receptions, the whole before just preserving in data buffer zone
Content, then empties data buffer zone.For example, data buffer zone is dimensioned to print the print data size of one page of content,
Data buffer area is full to be then considered that a complete print data is preserved.
3rd, print command strategy.If receiving OA, during the print command such as OB, OC, OD, 4A, then next printing is represented
