Setting the DIP Switches

By adjusting the settings of the two groups of DIP switches (SW1 and SW2) in the back of the printer, you can control various features such as character set and page length.

To change the setting of a DIP switch, first turn off the printer. Using a pencil, pen, or other pointed instrument, change the setting as shown below. Then, turn the printer back on.

The tables below describe the functions of the DIP switches

Printing on Special Paper

For printing on special types of paper, see the table below. When

the paper thickness lever is set to position 4 or higher, the MULTI-

PART light comes on and the printing speed is reduced.

The following table gives you general guidelines for selecting the

right paper thickness lever position to match your paper:

Selecting Character Sets

To make sure that the printing fits within this area, always perform a sample printing test using a normal single sheet of paper before printing on envelopes.

Now that you have set up and tested the LQ, you should make sure that it works with the application programs you want to use. Most application programs let you specify the type of printer you are using so that the program can take full advantage of the printer’s features. Many of these programs provide an installation or setup section that presents a list of printers from which to choose.

Choosing from a menu

Because the family of Epson printers shares a great many

commands, you can use an application program even if it does not

‘Adjacent dots cannot be printed in this mode.

Column reservation numbers

The graphics command requires more than one number to specify

how many columns to reserve because one line can use thousands of columns, but the LQ does not use numbers larger than 255 (decimal). Therefore, the graphics mode command uses two numbers for reserving columns.

To figure nl and n2, divide the total number of columns by 256.

The result is

n2;

the remainder is

ni.

Since the command is set up

for two numbers, you must supply two even if you need only one. When you need fewer than 256 columns, just make nl the number of columns you are reserving and make n2 a zero.
