Honor DSR
To determine whether the printer uses
the Data Set Ready (DSR) signal.
DSR is one of the handshaking signals
for most serial interface cables.
The serial interface uses DSR to
distinguish data sent by the computer
from data created by electrical noise in
the serial cable. This electrical noise
can cause stray characters to print.
Select On to prevent stray characters
from printing.
Off*
All data received by the serial port is
treated as valid data.
On
Only data received while the DSR
signal is high is treated as valid.
Job
Buffering
To temporarily store jobs on the printer
hard disk before printing.
Note: Changing the Job Buffering
menu item automatically resets the
printer.
Off*
Does not buffer print jobs to the hard
disk.
On
Buffers print jobs to the hard disk.
Auto
Buffers print jobs only if the printer is
busy processing data from another
input port.
