1.2.1.1 Receiving Buffer Full Operation
When receiving data via the parallel interface or the optional Type B interface
while in a state where no error has occurred (including the Pause state), if the
available capacity of the buffer drops to 4 KB or less, the printer receives at 1
byte/sec. and prevents the host from issuing a time out.
At the point when the available capacity of the buffer becomes 8 KB or higher,
1 byte/sec. reception is canceled and reception stops when the available
capacity is 32 bytes or less. At the point when the available capacity recovers
to 1K-byte or higher, reception at 1 byte/sec. is resumed.
Pin No.
