When the following conditions occur, the printer automatically turns off the appropriate motors and disables printing to prevent damage: • Paper out, cover off, or knife unable to home • Printhead too hot or voltages out of range The lights on the operator panel will signal when these conditions occur as well as indicate what state or mode the printer is in.
7193 Owner’s Guide Chapter 5: Communication Chapter 5: Communication Communication Overview In order for a receipt to be printed, a program must be in place that translates the data from the host computer into a language that the printer can understand. This program must tell the printer exactly how to print each character. This chapter describes how to create such a program or modify an existing one. Interfaces In order for the printer to communicate with the host, a communication link must be set up.
Chapter 5: Communication 7193 Owner’s Guide Using BASIC to Send Commands In BASIC, printer commands are sent as a string of characters preceded by the LPRINT command. For example, LPRINT CHR$(&H0A) sends the hexadecimal number 0A to the printer, which causes the printer to print the contents of its print buffer. Previously sent commands tell the printer exactly how this data should appear on the paper.
7193 Owner’s Guide Chapter 5: Communication The next table shows that with no delay between lines, the transmit time is much less than the print time, allowing the printer to print at full speed. Characters/Line Lines/Receipt Transmit Time: (9600 Baud) Transmit Time: (19.2 K Baud) Print Time 20 20 0.4 Seconds 0.2 Seconds 1.2 Seconds 20 40 0.8 Seconds 0.4 Seconds 2.4 Seconds 44 20 0.88 Seconds 0.44 Seconds 1.2 Seconds 44 40 1.76 Seconds 0.88 Seconds 2.
Chapter 5: Communication 7193 Owner’s Guide RS-232C Technical Specifications This section describes the pin settings for the connectors and the RS-232C interface parameters. The RS-232C parameters are selected by setting the DIP switches on the printed circuit board. See “RS-232C Switch Settings” on the next page for the position of the DIP switches. The RS-232C parameters must match those of the host computer.

Chapter 6: Commands 7193 Owner’s Guide Printer Status Commands For RS-232C printers, these commands enable the printer to communicate with the host computer following the selected handshaking protocol, either DTR/DSR or XON/XOFF. 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 RS-232C interface and not respond to either of the Printer Status commands.
93 Owner’s Guide Chapter 6: Commands Transmit Printer Status Sends status data to the host computer. This command is available only on RS-232C printers. Hexadecimal Decimal ASCII 1B 76 27 118 ESC v The printer sends one byte to the host computer when it is not busy or in a fault condition. See “Busy Line and Fault Conditions” in the following section, “Real Time Commands,” for details about fault condition reporting. See the table below. In DTR/DSR protocol, the printer waits for DSR = SPACE.

7193 Owner’s Guide Chapter 6: Commands Alternate Implementation The alternate implementation uses the DLE (Hex 10) sequences as implemented on Epson’s TM-T85™ and TM-U950™. An application using these DLE (Hex 10) sequences and the original 7193 Clear Printer command must distinguish for the printer between the new Real Time commands and the old Clear Printer command by adding a NUL (Hex 00) to the Clear Printer command.
Chapter 6: Commands 7193 Owner’s Guide 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. When the DLE sequences are being used, the last byte stored when the buffer fills up could be the DLE code, with no room for the subsequent EOT or ENQ.
