Setting the DIP Switches
The DIP Switch Functions
Auto line feed
When auto line feed is on (DIP switch 2-4 on), each carriage return
code (CR) is automatically followed by a line feed code (LF).
Input buffer capacity
The input buffer stores data from your computer. If you want to free
your computer for other tasks while the printer prints, change the
setting of switch 2-5 to 8 KB (on). Before using user-defined characters,
however, be sure to set the input buffer to 1 KB (off).
Tear-off mode
When DIP switch
2-2
is on, the short tear-off mode is on. This feature
automatically advances continuous paper to the tear-off position, and
then reverse-feeds the paper to the loading position. See the section on
using short tear-off later in this chapter.
CAUTION:
Do not use the short tear-off mode with labels.
Print direction of multi-pass characters
Multi-pass characters are normally printed unidirectionally. If DIP
switch 2-6 is on and ESC U0 is input, multi-pass characters are printed
bi-directionally.
