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 three host buffers—buffer #1, buffer #2 and
buffer #3—to simultaneously handle the print data on three 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 Fix, buffer #1 only stores data arriving at
the parallel interface; buffer #2 only stores data arriving at the option
interface (if installed); and buffer #3 only stores data arriving at the USB
interface. The default setting is Fix. When Host buffer mode is set to Auto,
the print data arriving from the computer is stored in whichever of the
three buffers is empty. As data begins arriving at the other interface, it is
stored in the other host buffer.
The size of each host buffer can be changed by using Host buffer size. The
factory setting is 500 KB for the total size of the three 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.
