1.6.4 Host buffer
Host buffer is the shared memory area in the printer's main memory that
temporarily stores print data sent from the host computer for each
interface. The printer has two host buffers—buffer #1 and buffer #2—to
simultaneously handle the print data on two interfaces. The way the host
buffers receive data can be changed by selecting
Host buffer mode
as
described below. The size shared for the host buffers can be adjusted by
changing the value for
Host buffer size
.
When
Host buffer mode
is set to
Auto
, the print data arriving from the
computer is stored in whichever of the two buffers is empty. As data begins
arriving at the other interface, it is stored in the other host buffer. When
Host buffer mode
is set to
Fix
, buffer #1 only stores data arriving at the
parallel interface; and buffer #2 only stores data arriving at the option
interface (if installed). The default setting is
Auto
.
The size of each host buffer can be changed by using
Host buffer size
. The
factory setting is 60 kB for the total size of both buffers and can be changed
using the PRESCRIBE FRPO H8 command (See the
Programming
Manual
on the CD-ROM for details). The total host buffer size can be
between 5 kB and the printer's free memory size.
