Switches 9 and 10 select printer/plotter devices at power-up.
The devices may be changed after power-up using Option
commands, or by using the MENU. Two EPSON® formats are
selectable. EPS7 uses seven print wires per head pass, and is
usually slower. It is the chr$(27)1L’ mode. EPS8 uses eight
print wires per head pass, and is usually the faster print-head
speed, it is the chr$(27) * Y* mode. In this mode most Epson
and Epson-compatible printers will not strike any print wire
more often than every second pixel. EPS8 is selected when
parity is disabled. Devices are selected with the following
switch positions:
