Input/Output
Parallel Interface
The Formatter PCA receives incoming data through its Bidirectional
interface (IEEE 1284). The I/O provides high speed and two way
communication between the printer and the host, allowing the user to
change printer settings and monitor printer status from the host
computer. The user may configure the HIGH SPEED item in the Control
Panel menu. The default setting, YES, allows the I/O to run at the
higher speeds supported by most newer computers. When set to NO,
the parallel interface runs at the slower mode that is compatible for
older computers. The user may also configure the ADVANCED
FUNCTIONS item. The default setting, ON, allows for two way parallel
communications. The OFF mode disables the advanced functionality.
The I/O is compatible with the Bi-directional parallel interface
standard.
Expanded I/O
The optional Expanded I/O card can be installed in the slots provided
on the Formatter PCA. It provides automatic I/O switching between
multiple computers or networks connected to the printer. The network
version printers include the HP JetDirect Multi-protocol Network Card
with Ethernet/10Base-T and 10Base-2, and LocalTalk.
Flash
Flash is provided in optional 2 and 4 MB flash memory DIMMs for
storage of forms, fonts, and signatures.
Disk
The optional 1.2 GB EIO-based hard drive is used for creating
multiple original prints (mopies) and storage of forms, fonts, and
signatures.
Local Talk I/O
The printer implements AppleTalk networking protocol through
LocalTalk hardware. The LocalTalk network cable (HP P/N 92215N) is
connected through the EIO card.
CPU
The Formatter PCA incorporates a 100MHz RISC processor.
