Installing the Printer
1.5 Connecting the Printer to a Computer System
NOTE: For specific information on cables, see Section A.2.
1.5.2 Communication Modes
The LA310 MultiPrinter has three different communication modes for sending
data that you can select. These communication modes affect the way in which
you connect to a computer system. The modes are:
• Communication through the serial port.
• Communication through the parallel port.
• Automatic port selection (the default setting). Under this setting, the
printer senses which interface is active, and automatically processes data
from the active port.
1.5.3 Protocols
The LA310 MultiPrinter supports the following protocols (each labeled on the
printer):
• DEC PPL2 (labeled DEC)
• IBM Proprinter III (labeled PP III)
• Epson FX-1050 (labeled FX), or an optional emulation protocol through a
cartridge
The protocol that you choose depends on the host software program that you
are using.
NOTE: The optional emulation protocol is not supplied with the printer.
1.5.4 Protocol Selection
There are different ways in which protocols are selected:
• By Set-up:
One of the available protocols is forced, regardless of the communica-
tions port used.
Protocol selection is port-dependent, with one of each of the available
protocols assigned to each port. By default, DEC PPL2 is assigned
to the serial port, and IBM PP III is assigned to the parallel port
(although this is the default setting, it can be configured differently
through Set-up).
• By manual selection, using the front panel.
• By software selection.
