  • Page 16: Introduction

    Introduction The Model 8900 Series Printers are compatible with a wide range of computers and application software. The printer menu structure enables you to select and alter the fundamental printer operating parameters to fit the requirements of your computer, its communication interface, and its application software.
  • Page 17 Note: The Model 8900 Series Printers User’s Manual (Part No. 2557785-0002) explains the basic use of the operator control panel and its associated menu structure. The Setup/Test switch on the control panel lets you enter the setup/ test menu. This menu consists of the following submenus containing most of the printer setup parameters and test features.

  • Page 18: Model 8900 Series Emulation Modes

    The emulation mode determines how the printer responds to commands from the host computer and determines the specific set of commands to which the printer responds. For example, if you select the TI 880 emulation mode, the printer emulates the functions of the TI Model 880 Printer and responds to the set of commands designed for that printer.

  • Page 19: Ti 880 Emulation

    The default setting is ON. Line Feed and Carriage Return Upon Receipt of LF When on, this parameter causes the printer to perform both a line feed (LF) operation and a carriage return (CR) operation upon receiving an LF command from the host computer.

  • Page 20: Line Feed And Carriage Return Upon Receipt Of Cr

    When on, this parameter causes the printer to print one line of expanded print after receiving a shift out (SO) command. When this parameter is off, the printer invokes the G1 character set into the GL area of the character table upon receiving SO. The default setting is OFF.

  • Page 21: Ti 855 Emulation

    LF operation automatically. The default setting for the automatic LF parameter is NO. IBM Proprinter XL and Epson FX Emulations The IBM Proprinter XL and Epson FX emulation submenus contain the same following parameters. Automatic Line Feed This parameter is identical to the automatic LF parameter described for the TI 855 emulation mode.

  • Page 22: Automatic Carriage Return

    CR command at the end of each print line. If the printer advances from print line to print line but fails to perform a carriage return operation, you need to turn on the automatic CR parameter.

  • Page 23: Interface Parameters

    The default setting is SERIAL. Buffer Size The buffer size specifies the number of data bytes that the printer’s receive buffer can store. The buffer size parameter can be set to 256, 4000, or 32,000 bytes. The default setting is 32,000.

  • Page 24: Baud Rate

    (See Chapters 3 and 10.) Data Bits The data bits parameter specifies whether the printer is to print 7- or 8-bit character codes. The default setting is 8. (Refer to Chapters 3 and 10 for information about 7- and 8-bit data.)

  • Page 25: Xon/Xoff (Transmit-On/Transmit-Off)

    The printer sends an XOFF (DC3 control character) when the initial busy condition occurs (buffer overflow) to indicate that it is busy. If the host continues to send data, the printer sends an XOFF approximately every 20 ms until the hosts stops sending data.

  • Page 26: Etx/Ack (End-Of-Text/Acknowledge)

    For the READY LOW setting the printer sets interface pin 11 low to indicate that it is ready to receive data and high to indicate that it is busy.

  • Page 27: Miscellaneous Setup Parameters

    The following figure shows the miscellaneous setup parameters submenu and the following paragraphs describe these parameters. Character Set The Model 8900 Series Printers character set repertoire includes 6 standard character sets and 11 international language versions. The default character set is IBM PC1 and the default international language version is U.S.

  • Page 28: Z-Axis Control

    The default setting is COLOR. Ribbon Adjust If the printer appears to be printing mixed colors or missing the upper or lower parts of the characters, the ribbon may need adjustment. The RIBBON ADJ parameter invokes a display that lets you adjust the ribbon up or down.

  • Page 29: Idle Delay

    At the end of a printing operation, if the paper is at top of form, the printer waits for more data and then, after a short delay (idle delay), moves the paper to the tear-off position. The IDLE DELAY parameter invokes a display that lets you adjust the idle delay to a value in the range of 300 milliseconds to 90 seconds.

  • Page 30: Graphics Printing Mode

    The PAPER OUT = BUSY parameter, when set to YES, lets the printer send a busy condition signal to the communication interface when the printer runs out of paper. The default setting is YES. Limiting Control Panel Operation This parameter enables you to select three levels of control panel functioning, intended to limit operator access to certain printer function.

    Serial interfaces transfer data in bit-serial fashion, one bit at a time. To provide communication compatibility with a wide range of systems, your printer offers a choice of any of the following standard and optional communication interfaces. Parallel interface, standard.

  • Page 195: Data-Transfer Operations

    (simplified block diagrams) The long-distance system typically uses telephone lines to transfer data from the host to the printer. Because this system is limited to bit-serial data-transfer operations, it is necessary that the host-to-modem interface at one end and the modem-to-printer interface at the other end be serial interfaces.
  • Page 196 3. The printer signals the host to suspend data transfer operations as the printer continues to transfer characters at a fixed rate from the receive buffer to the print mechanism. 4. When the supply of characters in the receive buffer is sufficiently depleted, the printer signals the host that it is ready to receive additional data.

  • Page 197: Parallel Communication Interface

    (shown in the following figure) that transfers both data and control signals between the printer and the host computer. The parallel interface connector is located at the rear of the printer and provides bail latches to secure the interface cable connector. The table on the following page lists the parallel interface signals, their names, their pin assignments, and their sources (host or printer).

  • Page 199: Data Signals

    Acknowledge Signal The acknowledge (ACK-) signal from the printer indicates to the host that the printer has received the last character sent and is ready to accept another character. Unless the printer is busy, as described in the following paragraph, the printer activates ACK- (sets it low) under any of the following conditions.

  • Page 200: Busy Signal

    The receive buffer is filled to capacity. The printer is in its offline state. The printer is out of paper or a printer error condition exists. One of the control panel menus has been invoked and the printer has not been returned to its online state.

  • Page 201: Paper-Empty Signal

    Verify Signal The verify signal confirms proper connection of the parallel interface cable between the host and the printer. The verify in (VFIN) and verify out (VFOUT) pins are connected together inside the printer to form a loopback circuit. The host sends VFIN to the printer and, if the cable is connected properly, the printer returns the signal as VFOUT.
  • Page 202 2. After writing the character to the interface, the host monitors the BUSY line to ensure that the printer is ready to receive a character. If BUSY is inactive, and the required data stabilization time has elapsed, the host activates STROBE- to begin the transfer cycle.
  • Page 203 3. The printer activates ACK- (e) to signal the host that the receive buffer has received the character. 4. If the character does not fill the receive buffer, the printer deactivates BUSY and ACK- (f) to notify the host that the transfer operation is complete.

  • Page 204: Initialize Sequence

    Initialize Sequence The initialize sequence is a host-generated power-up reset sequence. When the host activates INIT-, the printer performs the following sequence. 1. Interrupts any ongoing operation. 2. Assumes the offline state.

  • Page 205: Serial Communication Interface

    Activation of either FAULT- or PE also activates BUSY to indicate that the printer cannot receive data. If the host attempts to transfer a single character during this time, the byte remains on the interface data lines until the error condition is cleared. The printer neither prints the character nor activates ACK-.

    Data terminal ready Interface Connection You can connect your printer to the host computer either directly via an interface cable or through a system of modems and telephone lines with an interface cable at each end of the system. The setup menu structure provides settings (DIRECT CONNECT and MODEM CONNECT) for each of these choices.

    The protective ground (PG) line is connected directly to the power cord ground to provide protection for the equipment and personnel. Signal Ground The signal ground (SG) line is connected to the printer power supply ground to provide a common reference level for all interface signals except protective ground.

    In the DIRECT CONNECT mode, the printer ignores this signal. In the MODEM CONNECT mode, CTS must be on for the printer to send data. If the interface cable does not provide a connection to this pin, the printer holds CTS in its on state.

  • Page 209: Interface Data Transmission Rate

    Because data-transfer operations on the serial interface occur in a bit-serial fashion, the data transmission rate is measured in bits per second, commonly called the baud rate. To provide compatibility with a variety of systems, your printer offers the following range of baud rates. 300 bits per second...
  • Page 210 Parity bit — A bit immediately following the character bits that allows the printer to check the integrity of the received data. The setup menu allows you to select even, odd, mark, space, or no parity checking.

  • Page 211: Serial Interface Busy-Handling Protocols

    Flow-Control Busy-Handling Protocols These protocols are busy-handling protocols determined by the host that can be selected via the printer setup menu. The menu structure allows you to select either of the following flow-control busy-handling protocols or to set both protocols inactive.

    PIN 20 H:READY (pin 20 high on ready) — When you select this parameter, the printer activates DTR (interface pin 20) to indicate that it is ready to receive data and deactivates DTR to indicate a busy condition. This busy-handling protocol is also known as the busy-on-DTR protocol.

    The current loop (TTY) interface uses a four-wire, passive, neutral current loop which does not interfere with the standard serial interface. The printer can receive data via either interface, provided the other interface is in a spacing condition or its cable is disconnected.

    Z-Axis Adjustment Escape Sequence Introduction The Model 8900 Series Printers sense top, left, and right edges plus thickness when a form is loaded. These settings provide the location of printout on the form such as top, bottom, left, and right margins and locations of labels or uneven edges.
  • Page 215 Damage to the printer can occur by misuse of this command. Do not print across any boundary of a label or uneven edge (top, bottom, left, or right).
  • Page 216 Valid Z-axis adjustment values are 00 through 99 from the automatic Z-axis initialization adjustment (00) in positive or negative directions (-99 through +99). Note the location of the Z-axis initialization whenever paper stock is changed or tractors are moved, to determine the 00 calibration and corresponding number of sheets and form thickness.
