    Page length for tractor
    This setting allows you to set the page length for continuous 
    paper.
    Skip over perforation
    This feature is available only when continuous paper is selected. 
    When you select On
    , the printer provides a one-inch (25.4 mm) 
    margin between the last line printed on one page and the first line 
    printed on the next page. Because the program margin settings in 
    most applications override margin settings made from the control 
    panel, you should use this setting only if you cannot set your top 
    and bottom margins using your application.
    Auto tear off
    When auto tear off is on and you are using continuous paper with 
    the tractor, the printer automatically advances the paper 
    perforation to the tear-off position, where you can easily tear off 
    the printed pages. When the printer receives the next print job, it 
    automatically moves the unused paper back to the top-of-form 
    position and starts printing, so you can use all of the next page.
    When auto tear off is off and you are using continuous paper with 
    the tractor, you need to move the perforation to the tear-off 
    position by pressing the control panel button. See “Using the Tear 
    Off button” on page 2-15 for more information.
    Auto line feed
    When auto line feed is on, the printer accompanies each carriage 
    return (CR) code received with a line feed code, and the print 
    position moves to the next line. If the printer adds an extra line 
    after every carriage return, select Off
    .

    Print direction
    You can select auto print direction (Auto
    ), bidirectional printing 
    (Bi-D
    ), or unidirectional printing (Uni-D
    ). Printing is normally 
    bidirectional for faster printing; however, unidirectional printing 
    allows for precise vertical printing alignment, which is useful for 
    printing graphics.
    When set to Auto
    , the printer analyzes the data and uses 
    unidirectional printing only for any lines which require vertical 
    printing alignment.
    Software
    When you select ESC/P2
    , the printer operates in the EPSON 
    ESC/P2 mode. When you select IBM 2390 Plus
    , the printer 
    emulates an IBM printer.
    0 slash
    The zero character has a slash ( ) when this feature is on. It has no 
    slash (0) when this feature is off. The slash allows you to easily 
    distinguish between the uppercase letter “O” and a zero.
    High speed draft
    When you choose On
    , the printer prints up to 413 cps (characters 
    per second) at 10 cpi (characters per inch). When you choose Off
    , 
    the printer prints up to 310 cps at 10 cpi.0

    I/F (interface) mode
    The printer comes with a built-in parallel interface and an 
    interface slot in which you can install one optional interface. For 
    information on using an optional interface, see “Optional 
    interface cards” on page A-19.
    If your printer is connected to only one computer, select Parallel
     
    or Optional 
    for the interface mode, depending on the interface 
    you use. If your printer is connected to two computers, select 
    Auto
     (automatic) to allow the printer to automatically switch 
    between interfaces depending on which one is receiving data.
    Auto I/F (interface) wait time
    This setting takes effect only if an optional interface is installed 
    and the auto interface mode is selected. This setting determines 
    how long the printer waits when it no longer receives data from 
    an interface before it checks whether a print job is being sent 
    through the other interface. You can specify 10 seconds
     or 30 
    seconds
     for the auto interface wait time.
    Parallel I/F bidirectional mode
    The Parallel Interface bidirectional transfer mode is used when 
    this feature is on. If bidirectional transfer mode is unnecessary, 
    turn this off.
    Packet mode
    Select Auto
     to use the IEEE-1284.4 packet transfer mode. If packet 
    transfer mode is unnecessary, or if you cannot connect, turn this 
    off.

    Auto CR (carriage return)
    This setting is available only in IBM 2390 Plus emulation mode. 
    When auto carriage return is on, each line feed (LF) code or ESC 
    J code is accompanied by a carriage return code. This moves the 
    print position to the beginning of the next line. If the printer adds 
    an extra line after every carriage return, select Off
    .
    A.G.M. (Alternate Graphic Mode)
    When A.G.M. is on, the printer can use some advanced graphics 
    commands like those available in ESC/P2 mode. When you select 
    IBM 2390 Plus mode, this setting is available.
    Character table
    You can select from among 13 to 36 standard character tables, 
    depending on the country of purchase. See “Character tables:” on 
    page C-5 for more information of the tables.
    International character set for Italic table
    You can select among several international character sets for the 
    Italic character table. Each character set contains eight characters 
    that vary depending on the country or language, so you can 
    customize the Italic table to suit your printing needs.
    Font
    You can select six fonts in default-setting mode. The font selected 
    here is appears under Others
     in the control panel. The following 
    fonts are indicated on the control panel and can’t be selected by 
    default settings: Draft, Roman, Sans Serif, Courier, Prestige, and 
    Script.

    Manual feed wait time
    This sets the amount of wait time between when paper is inserted 
    into the paper guide and it is fed. If the paper feeds before you 
    can adjust its position to your satisfaction, you can increase the 
    wait time.
    Buzzer (beeper)
    The printer beeps when an error occurs. (See “Using the Error 
    Indicators” on page 5-2 for more information on printer errors.) 
    If you do not want the printer to beep when an error occurs, turn 
    this setting off.
    Overlapping forms (LQ-680Pro only)
    This setting takes effect only when the skip-over-perforation 
    setting is on. When overlapping-forms setting is on, the printer 
    lifts up the print head each time it makes a one-inch margin with 
    the skip-over-perforation feature. You need to turn on both the 
    overlapping-forms and the skip-over-perforation settings when 
    you use overlapping forms. This setting is available only on 
    LQ-680Pro. 
    Changing default settings
    Follow the steps below to enter the default-setting mode and 
    change the printer’s default settings.
    Note:
    o
    To print the language selection and default-setting mode 
    instructions, you need five sheets of A4 or letter size single-sheet 
    paper, or five pages of continuous paper that is at least 279 mm 
    (11 inches) long and 210 mm (8.27 inches) wide.
    o
    If you use single sheets without an optional cut-sheet feeder, you 
    need to feed a new sheet of paper each time the printer ejects a printed 
    sheet.

    change, describe how to change them, and show you how the 
    control panel lights help you make settings. Follow these 
    instructions to change the default settings using the buttons 
    on the printer’s control panel.
    Note:
    The arrows on the instruction sheets indicate the printer’s current 
    settings.
    5. When you finish making settings, turn off the printer and exit 
    the default-setting mode. Any settings you have made remain 
    in effect until you change them again. 
    Note:
    To exit the default-setting mode, turn off the printer when it has

    Problems and Solutions 
    Most printer problems are easy to solve. Use the information in 
    this section to find the cause and solution to any printer problems 
    that occur.
    Determine what type of problem occurred, and see the 
    appropriate page listed below:

    You can also use the self test feature to determine whether the 
    printer or the computer is causing the problem. See “Printing a 
    Self Test” on page 5-18 for instructions.
    To pinpoint communication problems, experienced users may 
    want to use the printer’s hex dump mode, described in “Printing 
    a Hex Dump” on page 5-19.
