(Example 4)
Buffer repeat count is 2.
(Example 5)
Timing of Fault : Print completed, Data count when error occurs : 2
(Example 6)
Timing of Fault : Print started, Data count when error occurs : 0
A communication buffer fault occurs because the number of data in the buffer is
2 after B is printed.(C and D in the buffer are not printed)
A communication buffer fault occurs because the number of data in the buffer
is 0 after B is printed followed by detection of print start signal.
