You can use the SelecType control panel to choose fonts, pitches, and
condensed printing. The settings you select using the SelecType panel
remain valid even after the printer is turned off. reset, or initialized.
However, commands from your software application program
temporarily override the SelecType settings.

International Character Sets

Selecting an international character set provides you with the characters
used in other languages. To obtain the desired international character set,
set switches 1-6, 1-7, and 1-8 according to the DIP switch table on page
3-7. The following table shows the characters that differ in each

international character set.

Cut sheet feeder mode

When DIP switch 2-2 is on, you can use your printer’s optional cut sheet
feeder. See Chapter 7 for more information on using a cut sheet feeder
with your printer.

Skip over perforation

When DIP switch 2-3 is on, a one-inch margin is provided between the
last line printed on one page and the first line printed on the next page.
When using continuous paper, this feature causes the printer to stop
printing, skip over the perforation, and then resume printing. If you

adjust your loading position correctly, you can get half of the margin at
the bottom of one page and half at the top of the next page. See the
section on adjusting the loading position later in this chapter.

Note: Most application programs take care of the top and bottom
margins. Only use skip over perforation if your program does not
provide these margins

Automatic line feed

When DIP switch 2-4 is on. a carriage return code (CR! causes an
automatic line feed. When it is off, line feeds occur only when the printer
receives line feed codes (LF). Since some computers and application
programs automatically add line feeds to carriage returns, the setting you

use depends on your computer and application program.

Default character set

When DIP switch 1-1 is on, the user-defined character set is the default.
User-defined characters are maintained in printer memory even when the
power is turned off, so the user-defined character set can be selected
simply by setting this switch to on. However, when this switch is on,
new user-defined characters cannot be defined. See Chapter 4 for more
information on user-defined characters. This switch is effective only in
the Epson ESC/P mode.

Zero character

When DIP switch 1-2 is on, the printer prints slashed zeroes (0). When
the DIP switch is off, the printer prints open zeroes (0). This is useful for
clearly distinguishing between uppercase O and zero when printing such
items as program lists.

Character table

When DIP switch 1-3 is on, the Epson Extended Graphics character table
is selected. When it is off, the italics character table is selected. The Epson
Extended Graphics character table contains international accented

characters, Greek characters, and character graphics for printing lines,
corners, and shaded areas. If you have an IBM@ computer or an IBM
compatible, select the Epson Extended Graphics table when you wish to
print the character graphics as they are displayed on the screen. Since the
character table setting affects only half of the character table, you can

The countries numbered 8 through 12 are available only through the
ESC R software command. See the Command Summary in Chapter 8.
Also, in IBM emulation mode (DIP switch 1-4 on), a character set
containing international characters (CG character table 2) is selected
whenever any one of DIP switches 14. 1-7, or 1-8 is set to off. If all three
switches are on, CG character table 1 is selected. See Appendix B.

Page length

When DIP switch 2-1 is on, the page length is set to 12 inches. When
it is off, the page length is 11 inches. Other page lengths can be set with

the ESC C and ESC C0 commands. See the Command Summary in
Chapter 8.

still print text if you have selected the Extended Graphics set. Also, you
can still print italics if you use the proper software command. If your
printer is in IBM emulation mode (DIP switch 1-4 on), the graphics
characters are available no matter which character table you select.
