PRINT FUNCTION (DIP) SWITCHES

There are 10 switches located on rear panel of the printer. These switches
allow you to customize some DMP 440 features for your own applications.

When you set Switch 1-1 to OFF before turning on the power, the DMP-440
selects Tandy codes. In this setting, the switches function as shown in 
Table 2. On the other hand, if you set Switch 1-1 to ON, the DMP-440 sel-
ects codes for the IBM mode. In this case, the switches function as shown
in Table 3.

For instance, in Tandy mode, you can select word processing mode (better 
print quality) or data processing mode (faster printing speed).

If you use the DMP-440 with the Color Computer, turn off power and set the
appropriate switches accordingly. The serial port is compatible with 
Color Computers only.

When you receive the DMP-440, all DIP switches should be set to OFF.

Remember! The printer's power must be off before you change any of the
switches.

To use IBM mode with the Color Computer, set the DMP-440 in Tandy mode and 
send the (27 33) code sequence from the computer in BASIC. See Chapter 4 
"Entering IBM mode."
