BUFFER OPERATION
Stylus Pro5000 starts sending BUSY signal when it acknowledges no
available area left in the buffer. When the host keeps receiving this signal
for a long time, it acknowledges as time out and stops sending data.
INTERFACE SELECTION
The printer has 3-built in interfaces; the parallel interface and serial
interface, and has 1 optional Type-B interface card slot. These interfaces
are selected manually by the default setting mode or selected automatically.
(However, it is necessary to set these settings within the maintenance mode
level 1 of the panel operation.)
T
Manual Selection:
One of three interfaces can be selected by the default setting mode.
