Notes
Buffer Print = I-Prime makes
printer print contents of buffer.
Line End = I-Prime makes
printer print to the end of the
current line.
Invalid = I-Prime
the signal is ignored.
Determines whether voltage is
supplied to pin 18.
Epson Emulation
Some interface cables are
wired so that the XT signal
always causes an automatic
line feed. The Invalid setting
eliminates this. Use the Valid
setting if the system uses the
XT signal for automatic line
feed.
Set to Yes to run the serial
interface diagnostic test.
To restore to full operation,
power OFF the printer. Press
and hold PRINT QUALITY and
PITCH and power ON the
printer.
This will place the printer in
Menu Mode. Then, change
this setting to NO for normal
operation.
