5.3 Feed Switch Function • When pressed once, paper feed of one line occurs based on the amount of line feed set by ESC 2 and ESC 3. However, paper feed is not available in the following cases. (1) When the FEED switch is set to disable by ESC c 5 (2) When paper-end detector detected no paper (3) With Head Up.
5.3.1 Self-printing 1) Function Function to enable the printer setting status to be verified by printing 2) Start of self-printing When the power is turned on with the FEED switch pressed and held in print ready state, printer status is printed on the roll paper. Explanation of printed item is as shown below. (1) Printer type name BD2-2220 (2) ROM version VX.
5.3.2 Hexadecimal Dump Printing 1) Function Prints the data sent from the host in hexadecimal code and the corresponding characters. 2) Starting hexadecimal dump With paper set and Head Up (or Platen Open), turn the power on while pressing and holding the FEED switch. Set Head Down (or Platen Close). Then “HEX dump print mode” is printed on the roll paper followed by the printing of data received thereafter in hexadecimal numbers and corresponding characters.
5.3.3 Memory Switch Setting Mode 1) Settable memory switch MSW1、MSW2、MSW3 2) Starting memory switch setting mode With paper set and Head Up (or Platen Open), turn the power on while pressing and holding the FEED switch and then press the FEED switch twice, set Head Down (or Platen Close) to start the setting mode. After the setting mode is started, the guidance of setting content and operation method is printed.
6. INTERFACES 6.1 Bidirectional Parallel Interface (IEEE1284) 6.1.1 Specification 1) Compatibility Mode (Host → Printer Communication: Centronics Compliant) (1) Outline Compatibility Mode is a standard of Centronics interface that has been used for long. (2) Specification Data transfer system: 8 bit parallel Synchronization: By the nStrobe signal supplied from outside Handshake: By the nAck signal and Busy signal Signal level: All signals are TTL compatible.
6.1.2 Description of Input/Output Signals 1) Input/Output Signals Explanation of input/output signals [1] Input/Output Signals (Compatibility Mode) (1) Input signals to the printer ・DATA0 ~ 7: 8 bit parallel signal (positive logic) ・nSTROBE: Strobe signal for reading out 8-bit data (negative logic) ・nRESET: Applies reset by the nRESET signal in Compatibility Mode. (Can be disabled by the setting:Msw3-3) Reset signal is invalid for nSelectIn/1284-Active “HIGH”.
・SELECT: Always non-active (“LOW”). ・nFAULT: Signal to set “LOW” when the printer is in the error state (negative logic). ・PE: Signal to be output with No paper or near-end state (by command setting) (positive logic) Note: When using a command followed by FROM writing, printer may temporarily become BUSY (DTR) at the time of write operation. In this case, as the printer cannot make any processing, data transmitted may possibly be discarded.
3) Timing chart (Compatibility Mode) Data input and print timing Power supply DATA T2 nSTROBE T6 T1 T3 T4 BUSY nACK (Note) T5 T1，T2，T3 T4 T5 T6 : : : : 0.5 µs MIN 270ns MAX 2.3 µs TYP 1200ms MIN (At power on) Figure Timing Chart Note: ACK output position can be changed to ACK in BUSY, ACK while BUSY, or ACK after BUSY by the setting of customize value. 4) Buffer full state Buffer full state is when the remaining capacity of input buffer is as shown below.
5) Reverse Mode (Nibble/Byte) mode allows status to be transmitted from the printer. (Using GS a, DLE EOT n, GS r, of GS I command) ・The transmitting buffer of the printer is 99 bytes. The host must transfer to Reverse Mode to prevent loss of status. Being in the Reverse Idle state is desired when using ASB. If this is not possible, always monitor the presence or absence of the transmitting data from the printer. The ASB not transmitted but accumulated is transmitted together (OR) with the latest status.
6.2 RS-232C Serial Interface 6.2.1 Specification 1) Synchronization: Asynchronous 2) Baud rate 2400, 4800, 9600, 19200, 38400, 57600, 115200 bps (User selection) 3) Word configuration Start bit: 1 bit Data bit: 7 bits or 8 bits (User selection) Parity bit: Odd, even, or no parity (User selection) Stop bit: 1 bit or more 4) Signal polarity RS-232C ・Mark ＝Logic ”1” (-3V to-12V) ・Space ＝Logic ”0” (+3V to +12V) 6.2.
・State to become BUSY 1．Period from Reset (including reset by NV memory write command, I/F signal, and test print command) or just after printer power on to printer operation ready state. 2．Under test printing 3．Input buffer full state (Refer to “(2) Buffer full state”.) 4．During Head Up (or Platen Open) 5．Under line feeding with FEED switch 6．Waiting for pressing FEED switch at the execution of macro 7．No paper state 8．Error state BUSY regardless of memory SW setting under the above 1 to 3 conditions.
2) Buffer full state Buffer full state is when the remaining capacity of input buffer is as shown below. Table Input Buffer Full Set Value Buffer Full Clear 4K bytes Remaining 128 bytes Remaining 256 bytes 45 bytes Remaining 16 bytes Remaining 26 bytes ・When the remaining capacity of input buffer is 0 byte, data received is read and discarded. 3) Data receive error When any of the following error occurs, data is printed as “?” or read and discarded (Msw1-4).
6.2.3 Connection to Serial Port 1) Connection to 25-pin/9-pin serial port CN1 25-pin Serial interface CN1 9-pin Serial interface *The above wiring is an example of standard connection to the host. If the cable is relayed, it is necessary to take such measures as connecting DTR/DSR and RXD/TXD reversely, etc. 2) Connection to other serial port To connect to the connector other than the above, verify the status of various signals and connect properly. 6.
