Buffer control RS- 232
The document printer has a 8192 byte print buffer, whose size cannot be chan-
ged. If there are less than 512 bytes of buffer free no more data is accepted and
the interface is disabled. Only when there are more than 1024 bytes available in
memory, the printer is ready to receive data again. Depending on the interface,
the line is controlled by the DTR/CTS hardware handshaking or by the XON/
XOFF software protocol.
