Buffer full
recovery
timing
When the available space for bytes in the print buffer
drops to 512 or 16 bytes,
data
entry is disabled. As the
printer prints the
data
in
the buffer, the vacant area for
bytes increases. When this vacant area reaches one of the
four values listed in the table below,
data
communication
is
resumed. These settings are selectable by using the
DIP switches.
