PRINT MASTER-TO-COMPUTER COMMUNICATION
NOTE: Print Master will provide full duplex communication between a
computer and printer which are connected through the unit. This
section is applicable only when a device that is connected to a printer
port is sending data back to a device connected to a computer port.
When Print Master is sending data to a computer through a computer
port and the computer cannot receive any more data, Print Master will
expect to see a low on the DTR line or receive an XOFF. When the
computer can receive more data, Print Master will expect to see a
high on the DTR line or receive an XON.
If Print Master receives an XOFF character from a computer, the unit
will buffer data received from the printer device up to 256 characters.
If the buffer fills, Print Master
will not
handshake with the printer
sending data to the computer.

Print Master has a special option to order for the HP 3000 mini
computer. When the HP 3000 sends an HP Laserjet inquiry
command, Print Master will respond with an ASCII 0 (30 hex).
Please contact BayTech for purchasing information (see
Section 10
