BD2-1220/1221 User’s Manual 7.2 Description of Input and Output Signals (1) RD This is a serial reception data signal. When a framing error, overrun error or parity error occurs, the data containing the error is printed as a “?”. (2) DTR When this signal is Ready, you can write data or commands into the input buffer.
BD2-1220/1221 User’s Manual 7.4 Data Structure Mark h0, h1, h2 Space Start bit Data bits (+ parity bit) Stop bit (1) Start bit Status is read again 1/2 bit after a negative transition from Mark to Space. If the status is at Space, it is recognized as a Start bit.
BD2-1220/1221 User’s Manual 7.6 Data Reception Control When the DTR/DSR control mode is selected, host data can be received if the DTR signal is at Space, while it is not receivable if the signal is at Mark. When the DTR/DSR control mode is deselected, host data can be received after XON is transmitted, while it is not receivable after XOFF is transmitted.
BD2-1220/1221 User’s Manual 8. ERROR HANDLING This section describes some typical errors that could be detected on the control board at power on (initialization) or during printer operation. Error status can be known from the nERROR and nPEOUT signals. (The following describes errors that are identified by LED lights.) In the event of an error, the BUSY (DTR), PE, FAULT, SELECT, or some other signals may be activated as well as the ERROR and/or PEOUT signals described in the following table.
BD2-1220/1221 User’s Manual 8.2 Error Details Memory Check Error: Activated if an error is detected at power on. Head Up: Activated if the print head is raised with the Head-Up lever. The printer stops printing and generates an ERROR signal. Head Overheat: Activated if the print head temperature exceeds approx.
BD2-1220/1221 User’s Manual 9. SPECIAL FUNCTIONS In addition to the standard print function, the control board has some special print features such as the Page Print, Test Printing, and Hexadecimal Dump capabilities. Also it allows for software revision and registration of user-defined fonts and logos.
BD2-1220/1221 User’s Manual 9.4 Software Revision The control board retains control software in its flash memory. Software revision can only be performed with a flash memory loader. For more details, read the User’s Manual supplied with the Flash Memory Loader. Caution: The update software is overwritten on the existing software.

BD2-1220/1221 User’s Manual APPENDIX 1. DESCRIPTION OF PAGE MODE The control board has two print modes: STANDARD and PAGE. In STANDARD MODE, the control board prints or feeds paper each time it receives a print or paper feed command. In PAGE MODE, when the control board receives print commands and/or form feed commands, it simply forwards them to the specified print area of memory.
Page 39
BD2-1220/1221 User’s Manual Print data is mapped in the print area as follows: (1) The print area is set by ESC+W. When the control board has finished all of the print and paper feed actions specified before receiving an ESC+W, the ESC+W sets the left end (As viewed facing the control board) as the start point (x0, y0) of the print area.
BD2-1220/1221 User’s Manual APPENDIX 2. IDENTIFICATION OF SEND STATUS Because the status sent from the control board has certain fixed bits, it is possible to identify to which command the status belongs. When using ASB (Automatic Status Back), however, the first byte of ASB should be checked, and then the three consecutive bytes except for XOFF should be treated as ASB data.
BD2-1220/1221 User’s Manual APPENDIX 3. DEVICE ID If the bidirectional communication feature is used on the parallel interface, the host can receive character strings that identify the types of devices attached to the interface. When the control board receives a request for a device ID from the host, it replies with the following device <00>...
