GENERAL DESCRIPTION
The M84Pro printer was designed for continuous industrial and commercial applications as selfevident with its uncompromising all-metal housing, 203 to 609 dpi resolution, and label width capacity up to 5 inches wide.
This printer uses standard SATO programming language with specific values for print resolutions. These values are specified in “dots” and will vary depending upon the printer resolution and the amount of memory available for label imaging.
The M84Pro was designed to be compatible with preceding M-8400 series printers. The main difference is how it receives the command sequence and how it responds to certain commands. Refer to the Operator and Technical Reference Manuals for additional information.

THEORY OF OPERATION
When activated, the media and ribbon (where applicable) are fed in conjunction past the print head by an integrated drive train. The drive train is electric, stepper motor driven, coupled to a gear configuration located on the left side of the printer chassis. Paper guides within the chassis assembly ensure that the media remains properly positioned during the printing process and is fed unimpeded through the front cover. The exhausted ribbon material is rewound onto a take-up core inserted onto drive-train driven spindles.
A series of strategically located sensors send signals to the processing unit. The processing unit in turn sends response signals to the various features based on programmed and received data. Correct signals initiate print head activity.

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. If it does not detect the correct IEEE1284 signals in the interface connection, it will automatically operate in the standard Centronics mode which is much slower. To use the IEEE1284 parallel interface to its fullest capability requires that the host also have an IEEE1284 compatible interface and that the two be connected with a cable that meets the IEEE1284 specification. If either of these two are not present, the data rate is reduced.
In order to provide flexibility in communicating with a variety of host computer systems all printers use a Plug-In Interface Module. The IEEE1284 Interface module is shipped with the printer unless another interface type is specified at the time of the order. The other interfaces available is a high speed serial interface, an Ethernet interface, wireless Ethernet, or an optional Universal Serial Bus (USB) Adapter.
The Parallel interface will probably be the most useful in communicating with IBM PCs and compatibles. The RS232C Serial interface allows connectivity to a number of other hosts. The USB interface allows the printer to be connected to a computer that supports peripherals attached to a USB bus. Up to 127 peripherals can be connected to a single USB port.
WARNING: NEVER CONNECT OR DISCONNECT INTERFACE CABLES (OR USE A SWITCH BOX) WITH POWER APPLIED TO EITHER THE HOST OR THE PRINTER. THIS MAY CAUSE DAMAGE TO THE INTERFACE CIRCUITRY IN THE PRINTER/HOST AND IS NOT COVERED BY WARRANTY.
RECEIVE BUFFER
The printer may be configured to receive a data stream from a singular or multiple print jobs. The single job print buffer is generally used by software programs that wish to maintain control of the job print queue so that it can move a high priority job in front of ones of lesser importance. The multiple job buffer, on the other hand prints all jobs in the order they are received by the printer, and the order of printing cannot be changed.
SINGLE JOB BUFFER
The printer receives and prints one job at a time. Each job must not exceed 2.95 MB.
M84Pro Service Manual |
PN: 9001113A |
Page 3-1 |
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.
With an empty receiving buffer, the status of DTR is “high” (in X-On status if using X-On/X-Off) meaning the printer is ready to receive data. When the receive buffer is holding 2.0 MB of data (1 MB from being full), DTR will go “low” (an X-Off is sent) indicating the printer can no longer receive data. This condition is called “Buffer Near Full.”
The receiving buffer will not be able to receive more data again until a “Buffer Available” condition occurs. This takes place when the receiving buffer has emptied so that only 1 MB bytes of data are being held (2.0 MB bytes from being full). At this time, DTR will go “high” or an X-On is sent to tell the host that it can again receive data.
All printer error conditions (i.e., label out, ribbon out) will cause the printer to go busy (DTR “low” or X-Off) until the problem is corrected and the printer is placed on-line. The printer will also be busy if taken off-line from the front panel.

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. For this reason, an interface cable and host interface conforming to the IEEE1284 specification must be present to fully utilize the speed capabilities. This interface also operates bi-directionally and can report the status of the printer back to the host.

X-Off characters or status data (bi-directional protocols). |
3 |
To Printer |
RD (Receive Data) - Data to the printer from the host computer. |
4 |
To Host |
RTS (Request to Send) - Used with Ready/Busy flow control to indicate an |
|
|
error condition. RTS is high and remains high unless the print head is open (in |
|
|
this case, RTS would return to the high state after the print head is closed and |
|
|
the printer is placed back on-line) or an error condition occurs during printing |
|
|
(e.g., ribbon out, label out). |
5 |
To Printer |
CTS (Clear to Send) - When this line is high, the printer assumes that data is |
|
|
ready to be transmitted. The printer will not receive data when this line is low. If |
|
|
this line is not being used, it should be tied high (to pin 4). |
6 |
To Printer |
DSR (Data Set Ready) - When this line is high, the printer will be ready to |
|
|
receive data. This line must be high before data is transmitted. If this line is not |
|
|
being used, it should be tied high (to pin 20). |

* This connection at the host side of the interface would depend upon the pin that is being used as the Ready/Busy signal by the driving software. Typically, on a PC, it would be either CTS (pin5) or DSR (pin 6) on a DB-25 connector.
READY/BUSY FLOW CONTROL
Ready/Busy is the hardware flow control method for the serial interface on the M-84PRO printers. By raising/lowering the voltage level on Pin 20 of the RS232C port, the printer notifies the host when it is ready to receive data. Pin 4 (RTS) and pin 20 (DTR) are the important signals on the printer for this method of flow control. The host must be capable of supporting this flow control method for it to function properly.
X-ON/X-OFF FLOW CONTROL
X-On/X-Off flow control is used whenever hardware (Ready/Busy) flow control is not available or desirable. Instead of a voltage going high/low at pin 20, control characters representing ìPrinter Readyî (X-On =11 hexadecimal) or “Printer Busy” (X-Off = 13 hexadecimal) are transmitted by the printer on pin 2 (Transmit Data) to the host. In order for this method of flow control to function correctly, the host must be capable of supporting it. X-On/X-Off operates in a manner similar to the function of pin 20 (DTR) as previously explained. When the printer is first powered on it sends an X-Off when the “Buffer Near Full” level is reached and a X-On when the data level of the buffer drops below the “Buffer Available” mark. When the printer is taken off-line manually, it transmits an X-Off indicating it cannot accept data. When it is placed back on line manually, it sends an X- On, indicating it is again available for receipt of data. If an error occurs during printing (paper out, ribbon out), the printer sends an X-Off as soon as an error condition is detected. When the error is cleared and the printer is placed back on-line, it transmits an X-On indicating it is again ready to accept data. Upon power up if no error conditions are present, the printer will continually send X-On characters at five millisecond intervals until it receives a transmission from the host.

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 (<ESC>A . . Job#1 . . <ESC>Z<ESC>A . . Job#n . . <ESC>Z). An example of this would be: <ESC>A . . Job#1 . . <ESC>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. It requires a driver (shipped with each printer that has the interface installed) that must be loaded on your PC and the PC must be configured to support USB peripherals using Windows 98 or above. Details for loading the USB driver are contained in the USB Interface Manual that is shipped with each printer with a USB Optional interface installed. Up to 127 devices may be connected to a USB port using powered hubs.

BI-DIRECTIONAL COMMUNICATIONS
This is a two-way communications protocol between the host computer and the printer, thus enabling the host to check printer status. When Bi-Com 4 communications is selected, there is no busy signal from the printer. The host must request the complete status from the printer, including ready/busy. The host may request status in two different ways.
ENQUIRE/ACK/NAK
In the Bi-Com 4 mode, the host transmits an ENQ (05 hexadecimal) to the printer and the printer will respond with its status within five milliseconds. If printing, it will respond upon finishing the current label, then resume printing. In order for this protocol to work properly with an RS232C
M84Pro Service Manual |
PN 9001113A |
Page 3-6 |
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. The status information is defined as follows:
<STX>{ 2 Byte ID}{1 Status Byte}{6 Byte Label Remaining}{16 Byte Job Name}<ETX>
|
STREAM IDENTIFICATION |
|
ID |
|
Is a two byte number identifying the current print job ID. The |
|
|
print job ID is defined using the <ESC>ID Job ID command |
|
|
transmitted with the print job (see Job ID Store in the |
|
|
command listing for more information on how to use this |
|
|
command). The range is from 00 to 99. |
Status |
|
A single byte defining the current status of the printer (see the |
|
|
Status Byte Definition table). |
Label Remaining |
|
Six bytes defining the number of labels remaining in the current |
|
|
print job. The range is from 000000 to 999999 labels. |
Job Name |
|
16 bytes of ASCII characters identifying the name assigned |
|
|
to the job by the <ESC>WK Job Name command. If the Job |
|
|
Name is less than 16 characters, the field will be padded |
|
|
with leading zeroes. |
|
|
If an ENQ is received after the print job specified in the ID |
|
|
bytes has been completed, or there is no data in the buffer, |
|
|
the printer will respond with two “space” characters (20 |
|
|
hexadecimal) for the ID number, six “zero” characters (30 |
|
|
hexadecimal) in the Remaining Labels bytes and the 16 |
|
|
byte Job Name. |
CANCEL (CAN)
If a CAN (18 hexadecimal) command is received, it will stop the print job and clear all data from the receive and print buffers. A delay of five milliseconds or more is required before any new data can be downloaded. The CAN command is effective immediately upon receipt, even if the printer is off-line or in an error condition. The printer will return an ACK (06 hexadecimal) if there is no printer error condition and a NAK (15 hexadecimal) if an error condition exists.
PRINT JOB
Upon receipt of a valid print job (<ESC>A . . . <ESC>Z), an ACK (06 hexadecimal) will be returned by the printer if there are no errors and a NAK (16 hexadecimal) if a printer error exists.
M84Pro Service Manual |
PN: 9001113A |
Page 3-7 |
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. Upon receipt of this command an ACK (06 hexadecimal) is returned if there are no errors and a NAK (16 hexadecimal) if a printer error exists.
Note: To provide compatibility with older SATO printers, the RS232C interface can be configured to use an earlier Bi-Com 3 ENQ/ACK/NAK protocol selected via DSW2-8 and DSW1-7/8 (on the RS232 Interface module).The earlier protocol did not have provisions for the Job Name and did not respond to the DLE or DCI commands. Also, there are additional Response Codes in the Status Byte Definition. It is recommended that you use the current protocol rather than the earlier version unless it is necessary for compatibility with existing software.
