3 INTERFACE BOARD FEATURE

3.1 Plugging & Connecting Your Printer

3.1.1 Connecting the power supply

To the printer

To the power network

The power supply should be a “SELV” type in order to meet safety standards.

Product conformity validated with the Axiohm 3107329 power supply, in case of replacement, an equivalent model must be used.

Use of an inappropriate cable or power supply may seriously damage your printer and affect safety standards of the printer. The power supply main connector should be accessed to enable power disconnection.

The power supply cable connection to the printer must remain available during printer operation.

3.1.2 Connecting the terminal

Connections have to be set at the rear of printer: open the rear door and set the power supply and the interface cable as shown on the following drawing.

PCPR Printer User Manual Page 12 / 68 Reference: FDE – 3108010 Issue Z

3.2 Communication’s Management

Both RS232 and USB communication’s interfaces are implemented. The default communication mode is USB, if the USB is not connected, the RS232 is the applied interface.

Communication interfaces are SELV

3.2.1 RS232

The parameters of this interface will be following them:

These parameters will be stored in EEPROM and could be adjusted by control code sequences.

*: By default, these are the RS 232 communication interface parameters.

3.2.1.1 XON/XOFF Protocol

The XON/XOFF characters controls the information transfer between the printer and the host computer. The printer sends an XON character when it is ready to receive data and it sends an XOFF character when it cannot accept any more data. The software on the host computer must monitor the communication link as shown in the following flowchart in order to send data at the appropriate times. If XON/XOFF has been selected, the printer also toggles the DTR signal, as described in the next section, but it does not look at the DSR signal to transmit data.

XON character = hexadecimal 11.

XOFF character = hexadecimal 13.

3.3 Print Specification

3.3.1 Print density and density of receipt print lines

This function makes it possible to adjust the energy level of the print head to darken the printout. An adjustment should only be made when necessary. The factory setting is 100%. Warning: Choose an energy level no higher than necessary to achieve a dark printout. Failure to observe this rule may result in a printer service call or voiding of the printer warranty. Consult your Axiohm technical support specialist if you have any questions. When printing lines at high dot coverage (text or graphics), the printer automatically slows down to limit power consumption.

3.3.2 Duty cycle restrictions (printing solid blocks)

There are restrictions on the duty cycle because of the heat generated by the receipt thermal print head when printing solid blocks (regardless of the length of the block in relation to the print line). The restrictions are ambient temperature, the percentage of time (measured against one minute) of continuous solid printing, and the amount of coverage. Caution: When the duty cycle approaches the limits shown in the table, the receipt print head will heat up. If print head temperature exceeds 65 °C, a safety feature will shut down the print head to prevent damage.

Another cause for duty cycle restriction is paper feed motor temperature increase due to continuous printing.

The maximum duty cycle for a typical receipt is 23%.

This value is defined for all the range temperature.

Sets up to 32 horizontal tab-position n columns from column one, but does not move the print position. See the Horizontal Tab command (09).

The tab positions remain unchanged if the character widths are changed after the tabs are set. The command ends with hexadecimal 00; hexadecimal 1B 44 00 clears all tabs.

Formulas:

Set the tab positions in ascending order and put Hex 00 at the end. Hex 1B 44 00 (number of tabs not specified) clears all tab positions.

Hexadecimal

1D 23 n

Decimal

29 35 n

Operand:

n = mode selection

Range of n:

0 – 63

Description:

Selects a logo to be defined or printed. The active logo n remains in use until this command is sent again with a different logo n, or command 1B40 is sent or printer reboots.

When this command precedes a logo definition, that definition is stored in flash memory as logo n. If there is already a different definition in flash memory for logo n, the first is inactivated and the new

definition is used. The inactive definition is not erased from flash and continues to take up space in flash memory.

When this command precedes a logo print command and n is different from the previously active logo selected, the printer retrieves the logo definition for n from memory and prints it. If there is no definition for logo n, then no logo is printed.

Note:

An application using multiple logos, into flash memory, is responsible for erasing the flash memory page when the logo area is full.

Description:

Erases a section of user flash memory and sends a carriage return when the operation is complete.

This command erases all 48K Flash memory sectors allocated to logos storage and fonts storage.

Those sectors should be erased: when the logo definition area is full and an application is attempting to define new logos. All logo definitions are erased and must be redefined.

Important:

While erasing flash memory, all communication is disabled. To provide feedback to the application, the printer responds to the application when the erase is complete

by sending (0D). After sending the Erase User Flash Sector (1D 40 n) command, an application should wait for the response from the printer before sending data. Otherwise, data will be lost.

If an application is unable to receive data, it should wait a minimum of five seconds after sending the Erase User Flash Sector (1D 40 n) command before sending data.

6.1.11 Printer Status Commands

These commands enable the printer to communicate with the host computer. They are stored in the printer's data buffer as they are received, and are handled by the firmware in the order in which they were received.

When a fault occurs, the printer will go busy at the communication interface and not respond to either of the Printer Status commands. If the fault causing the busy condition can be cleared, such as by loading paper, or letting the thermal print head cool down, the printer will resume processing the data in its receive buffer.

Real Time commands allow the printer to respond immediately, even though it is busy at the communication interface. See the following section, Real Time Commands, for details about these commands.

6.1.12 Real Time Commands

6.1.12.1 Rules for Real Time Commands

Applications should not let the buffer fill up with Real Time commands when the printer is busy at the communication interface. A busy condition can be determined by bit 3 of the response to DLE EOT 1. Other responses to DLE EOT n can determine the reason for a particular busy condition.

Although the printer responds to Real Time commands when it is busy, it will place them into the buffer behind any other data there, and flush them out in the order in which they were received. When the printer is busy due simply to buffer full (that is, it can’t print data as fast as it can receive it), then data continues to be processed out of the buffer at approximately print speed and the Real Time commands will eventually get flushed out.

When the printer is busy due to an error condition, then data stops being processed of the buffer until the condition clears one way or another. In either case, but more quickly in the case of an error condition, the buffer can fill with Real Time commands.

To guard against this situation, the application must determine the cause of a busy condition and take appropriate action or pace the Real Time commands to avoid filling the buffer. There is a minimum of 256 bytes available in the printer’s buffer when it goes busy.

6.1.12.2 Moving Data Through the Buffer

6.1.12.3 Busy Line Fault Conditions

If the printer is in error condition (cover is open, paper is exhausted…), the printer will go busy immediately. Then it will stay busy and stop processing data out of the receive buffer until the condition clears. It will respond to the Real Time commands as described below.

6.1.14 Flash Firmware Download Commands

These commands are used to load firmware into the printer.

There are three ways to enter the download mode:

1. Powering the printer up with: pin J2.5 and pin J2.6 connected.

2. While the printer is running normally, send the command, “Switch to Flash Download Mode (1B 5B 7D)” to leave normal operation and enter the download mode.

3. If the Flash if found corrupted during Level 0 diagnostics the download mode is automatically entered after the printer has reset.

The printer never goes directly from the download mode to normal printer operation. To return to normal printer operation either the operator must turn the power off and then on to reboot or the application must send a command to cancel download mode and reboot.

When each flash download command is received, the printer returns either ACK or NAK to the host computer when each command is received:

ACK (hexadecimal 06) Sent when the printer has received a host transmission and has completed the request successfully. NAK (hexadecimal 15) Sent when a request is unsuccessful.

The commands are listed in numerical order according to their hexadecimal codes. Each command is described and the hexadecimal, decimal, and ASCII codes are listed. Communicates to the printer information downloaded from applications. Data is downloaded to flash memory to query the state of the firmware, calculate the firmware CRC and other functions.

6.1.14.1 Firmware Download Sequence

By providing a set of low-level commands, great freedom of implementation is given to customer application to customize the sequence to match its specific requirements.

Following is the description of a typical Firmware download sequence. Only the main steps are mentioned. Error checking and error recovery is not described:

1) Switch to Flash Download Mode

2) Check Flash Memory Size

3) Erase all Flash Memory sectors, except Boot Sector

4) Download Code to Active Flash Sector

4.1) Select Flash memory sector #n (each sector contains 64kbytes)

4.1.1) Program segment of N bytes

4.1.2) if more segments, loop back to 4.1.1)

4.2) if more sectors to program, loop back to 4.1)

5) Check Flash CRC

6) Reboot Printer
