[. . . ] Printers /LQH-HWTM User's Guide LineJetTM Printers User's Guide READ THIS SOFTWARE LICENSE AGREEMENT BEFORE USING THIS PRINTER Software License Agreement CAREFULLY READ THE FOLLOWING TERMS AND CONDITIONS BEFORE USING THIS PRINTER. USING THIS PRINTER INDICATES YOUR ACCEPTANCE OF THESE TERMS AND CONDITIONS. IF YOU DO NOT AGREE TO THESE TERMS AND CONDITIONS, PROMPTLY RETURN THE PRINTER AND ALL ACCOMPANYING HARDWARE AND WRITTEN MATERIALS TO THE PLACE YOU OBTAINED THEM, AND YOUR MONEY WILL BE REFUNDED. Definitions. "Software" shall mean the digitally encoded, machine-readable data and program. The term "Software Product" includes the Software resident in the printer and its documentation. [. . . ] These options and available settings are outlined in the following paragraphs. Data Bit 8 · · Enable. Allows access to the extended ASCII character set. The printer interprets bit 8 of each incoming data character as a zero, regardless of its actual setting. PI Ignored The PI (Paper Instruction) signal is used to control vertical paper motion. · · Enable. Ignores the PI signal and treats the data as characters or control codes. Causes the printer to interpret the eight data lines as VFU commands when the PI signal is true. 81 Chapter 3 HOST INTERFACE Data Polarity The Data Polarity parameter must be set to match the data polarity of your host computer. · · Standard. Does not expect the host computer to invert the data. Expects the data received on the data lines from the host computer to be inverted. Ones become zeros, and vice-versa. Response Polarity The Response Polarity parameter must be set to match the response polarity of your host computer. This option sets the polarity of the Acknowledge, Online, Fault, Paper Empty, and Busy signals. · · Standard. Inverts the response signals sent to the host computer. Busy on Strobe · · Enable. Asserts a busy signal after each character is received. Asserts a busy signal only when the print buffers are full. Latch Data On The Latch Data On parameter specifies whether the data is read on the leading or trailing edge of the data strobe signal. Prime Signal · · Disable. The parallel port does not perform a warm start (reboot) if the host asserts the prime signal. The parallel port performs a warm start (reboot) if the host asserts the prime signal. TOF Action · Reset. A form feed is performed before a warm start when the prime signal is asserted from the host. This setting is used only if the Prime Signal parameter is enabled. No form feed is performed on reset. · Buffer Size in K Configures the amount of memory allocated for the Centronics parallel port buffer. The default is 1 Kbytes, but you can specify between 1 and 16 Kbytes, in 1-Kbyte increments. 82 Serial Submenu Serial Submenu Note The serial parameters in the printer must be set the same as the interface in the host computer (at the other end of the data cable of the printer). Otherwise, the printer might not work online, and data characters from the computer might not print or might print as "garbled" text. * = Factory Default Serial (from page 79) Interface Type RS-232* RS-422 Data Protocol Baud Rate Word Length Stop Bits 1* 2 Parity XON/XOFF* ETX/ACK ACK/NAK DTR 600 1200 2400 4800 9600* 19200 38400 8* 7 None* Odd Even Mark Sense Data Term Ready True* Online and BNF Offline or BF False Request To Send Online and BNF* Offline or BF False True Buffer Size in K 1* (1-16) The serial submenu allows you to choose the configuration of the Serial host interface type, as shown above. Several other serial parameters are included on this menu, as shown below and described in the following pages. Interface Type Allows you to select either the RS-232 (the default) or RS-422 serial port interface. 83 Chapter 3 HOST INTERFACE Data Protocol You can select one of the following serial interface protocols to meet the host interface requirements. · XON / XOFF. The printer controls the flow of communication from the host by turning the transmission on and off. In some situations, such as when the buffer is full or the timing of signals is too slow or too fast, the printer will tell the host to stop transmission by sending an XOFF character. [. . . ] set To turn on, activate, invoke, or enable. 157 Appendix F SFCC Abbrev. The first character in a printer command sequence. In P-Series emulation mode, you can select one of five characters as the SFCC. In Epson FX and Proprinter emulation mode, the SFCC must always be the ASCII ESC character. [. . . ]
