<p>PURPOSE: To shorten the transfer time of data by optimizing a queuing time set for a data signal, etc. CONSTITUTION: A printer 2 is provided with a state transition time measuring circuit 29 which detects the rise and fall of a received signal to count timing, and count data obtained by counting the rise and fall timing of the test data, the data signal, and an STB signal by the state transition time measuring circuit 29 are totalized and sent to a personal computer 1, which calculates a minimum queuing time on the basis of the count data and sets the calculated minimum queuing time to transmission timing.</p> |
