Receive buffer control 2.7.1
There are following two factors for detecting buffer near full due to information such as receive, print, cancel are controlled by
each items.
Cause of receive buffer near full
(1) Buffer near full occurs when the remaining capacity of receive buffer (2.95MB) becomes 0.95 MB.
(2)Buffer near full occurs when the remaining capacity of history buffer (500 items) becomes 50 items.
Factors to release receive buffer near full
(1)Receive buffer near full is released when remaining capacity of the receive buffer becomes 1.95 MB or more.
(2)Receive buffer near full is released when remaining capacity of the history buffer becomes 200 items or more.
*Buffer-over occurs when the history buffer becomes full state (more than 499 items).
*Each history information is handled as an empty area when item analysis is finished.
