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. When the computer can receive

more data, Print Master will expect to see a high on the DTR line.

If Print Master sees a low on DTR from a computer, the unit will buffer

data received by the printer device up to 256 characters. If the buffer

fills, Print Master will not handshake with the printer sending data to

the computer.
