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.
