DIP Switches DIP-switch functions This section describes the different features you can control with the printer’s DIP switches. International character sets You can choose from eight international character sets by setting DIP switches l-l, 1-2, 1-3, and 1-4, according to DIP-switch Table 3.
DIP Switches Print direction for graphics The printer ordinarily prints text bidirectionally for speed and prints graphics characters unidirectionally for precise vertical alignment. You can, however, change text printing to unidirectional with the software command ESC U 1.
DIP Switches Skip-over-perforation Turning DIP switch 1-8 on when you are using continuous paper enables the skip-over-perforation function. Use this function to leave a one-inch (25.4 mm) space between the last printable line on one page and the first printable line on the next page so that the printer skips over the perforation.
DIP Switches Auto line-feed When auto line feed is on (DIP switch 2-4 on), the printer follows each carriage-return code (CR) received with a line feed code (LF). If your printer is double spacing, turn DIP switch 2-3 off. If each line overprints the next, turn DIP switch 2-4 on.
Micro Feed The micro-feed feature allows you to move the paper forward or backward in 1/180-inch increments. You can use this feature to adjust the loading and tear-off positions. When you make adjustments to the loading or tear-off positions for continuous paper, the printer remembers the new position even if you turn off the printer.
Micro Feed 2. While holding down the ALT button, press the LOAD/EJECT button to feed the paper forward or press the LF/FF button to feed the paper backward, as indicated by the arrows above the buttons. Adjusting the loading position The loading position is the position of the paper after it is automatically loaded by the printer.
Micro Feed 3. While holding down the ALT button, press the LOAD/EJECT button to move the loading position down on the page, or press the LF/FF button to move the loading position up on the page. The printer remembers the new loading position and advances all subsequent pages to the new position.
Tear Off After you finish printing, the tear-off feature advances continuous paper to the tear-off edge of the printer. You can then easily tear off printed sheets. When you resume printing, the printer automatically feeds paper back to the loading position.
Tear Off 3. Print on continuous paper loaded on the front or rear tractor (as described in Chapter 2). When you finish printing, the printer advances the final printed page to the tear-off position.
Tear Off Adjusting the tear-off position If the paper’s perforation does not meet the tear-off edge, follow the steps below to adjust the tear-off position: 1.
Typestyles You can produce a wide range of typestyles by selecting different character fonts, widths, and other enhancements from the control panel. The font names on the control panel are meant as guides only; your actual printed results may differ slightly in appearance.
Typestyles Roman AA AAAA A Sans serif A A AAAAA There are two printing speeds for the draft font; high-speed draft and normal draft, controlled by the DIP switch 1-6 setting. The following shows sample characters for each font. Normal Draft (DIP switch l-6 OFF) '"#$%&'()*+,-.
Typestyles Epson Sans Serif !“#$%&‘()*+,-./0123456789:;<=>?gABCDEFGHIJK LMNOPQRSTUVWXYZ[]^-‘abcdefghijklmnopqrstuv WX~~{:}-~CU~~BBB~~~~~~~~A~~~&~~~~~~~~~~~~~~ Epson Sans Serif proportional !“#$%&‘()*+,-.
Typestyles Character pitch You can select a character pitch from the control panel. To select a pitch, press the PITCH button until the indicator light next to the desired pitch comes on. The table below shows the character pitches available for each font.
