INTERFACE SPECIFICATIONS 3 This section presents the interface specifications and include detailed information on how to properly interface the printer with the host system. INTERFACE TYPES The parallel interface is a high speed, bi-directional interface that conforms to the IEEE1284 specification (ECP mode on some computers). The interface is also compatible with the older Centronics parallel interface standard.
Section 3: Interface Specifications MULTIPLE JOB BUFFER The printer is able to continuously receive print jobs while compiling and printing other jobs at the same time. It acts much like a “print buffer” to maximize the performance of the host and the printer. When using the RS232C Serial interface, the multiple job buffer uses either the Ready/ Busy with DTR (pin 20) or X-On/X-Off flow control protocols. See these sections for more details.
Section 3: Interface Specifications IEEE1284 PARALLEL INTERFACE The parallel interface for the M-84PRO printers is a Plug-In Interface Module that can be installed by the user. It conforms to the IEEE1284 specification. It will automatically detect the IEEE1284 signals and operate in the high speed mode. If it does not detect the IEEE1284 signals, it will operate in the standard Centronics mode, which is significantly slower.
Section 3: Interface Specifications RS232 SERIAL INTERFACE The High Speed Serial Interface is a Plug-In Interface Module that can be installed in the printer by the user.
Section 3: Interface Specifications RS232C SERIAL INTERFACE SIGNALS PIN 20 DIRECTION SIGNAL DEFINITION To Host DTR (Data Terminally Ready) - This signal applies to Ready/Busy flow control. The printer is ready to receive data when this pin is high. It goes low when the printer is off-line, either manually or due to an error condition, and while printing in the single job buffer mode. It will also go low when the data in the buffer reaches the buffer near full level.
Section 3: Interface Specifications DATA STREAMS The data streams for X-On/X-Off and Ready/Busy flow control are constructed in the same way as they are for Ready/Busy flow control (A . . Job#1 . . ZA . . Job#n . . Z). An example of this would be: A . . Job#1 . . Z. All characters are in ASCII. UNIVERSAL SERIAL BUS (USB) ADAPTER The Universal Serial Bus (USB) interface is a Plug-In Interface Module that can be installed by the user.
Section 3: Interface Specifications Optional Interface, pin 6 (DTR) and pin 5 (CTS) must be held high by the host. One way to ensure these pins are always in the correct state is to tie pin 20 (DTR) to pin 6 (DSR) and pin 4 (RTS) to pin 5 (CTS) at the printer end of the cable. ENQUIRE (ENQ) Upon receipt of an ENQ command, the printer responds with 25 bytes of status information bounded by an STX/ETX pair. The Bi-Com protocol works only in the multiple job buffer mode.
Section 3: Interface Specifications PRINT STOP (DLE) If a DLE (10 hexadecimal) is received by the printer, the print process is stopped and an ACK (06 hexadecimal) is returned if there are no errors and a NAK (16 hexadecimal) if a printer error exists. PRINT START (DC1) If the printer has been stopped by receipt of a DLE (10 hexadecimal) command, it can be restarted by sending a DC1 (hexadecimal 11) command.
