COMPUTER-TO-PRINT MASTER-TO-PRINTER COMMUNICATION

When a computer transmits data to a printer through a Print Master
computer port, the data is received and stored in the buffer which in
turn retransmits it to the printer through a printer port. During
transmission, after the buffer fills to where there is only 4K of memory
remaining, Print Master will make the computer port's CTS
(Clear-to-Send) line low (negative voltage), signaling the computer
that it cannot accept any more data. However, Print Master can
accept another 4K before overflowing the buffer.

When the buffer empties to where more than 4K remains (Print
Master's buffer outputs 4K blocks of data), Print Master will make the
CTS (Clear-To-Send) line high (positive voltage), signaling the
computer that it can accept more data.

When Print Master retransmits the data to the printer and the printer
cannot receive any more data, the unit will expect to see a low on the
DTR (Data Terminal Ready) line. When the printer can receive more
data, Print Master will expect to see a high on the DTR line.
