DISCUSSION
LaserWriter IISC
There are two SCSI connections on the rear of the printer; they are not parallel connectors. The LaserWriter IISC communicates with a Mac OS compatible computer via SCSI and follows standard SCSI rules. If it is the only SCSI device connected, one port must be terminated, while the other port accepts the SCSI cable that goes to the computer. (The ports are the same; it does not matter which port gets the terminator and which gets the cable.) There is no support for printing to a DOS/Windows compatible computer.
LaserWriter IINT
The Apple Desktop Bus (ADB) connector is not used on this printer. The 25-pin connection allows serial communication with a DOS/Windows computer; you can change communication rates and protocols via the Switch Bank. The mini DIN-8 connector allows AppleTalk communication with Mac OS compatible computers via LocalTalk connectors. This printer does not support simultaneous communications.
LaserWriter IINTX
The Apple Desktop Bus (ADB) connector is not used on this printer. The 25-pin connection allows serial communication with a DOS/Windows computer; you can change communication rates and protocols via the Switch Bank. The mini DIN-8 connector allows AppleTalk communication with Mac OS compatible computers via LocalTalk connectors. The SCSI connector is used for external hard drives to store downloaded font files; the SCSI connector is not used for SCSI printing directly from a Macintosh. This printer does not support simultaneous communications.
LaserWriter IIf
The LaserWriter IIf supports AppleTalk connections through the mini DIN-8 port to Mac OS compatible computers via LocalTalk connectors. The 25-pin port supports serial communication with DOS/Windows computers. The push button switch is used to change the communication rates and protocols for only the 25-pin port. The SCSI connector is used for external hard drives to store downloaded font files; the SCSI connector is not used for SCSI printing directly from a Macintosh. This printer does support simultaneous communications.
LaserWriter IIg
The LaserWriter IIg supports AppleTalk connections through the mini DIN-8 port to Mac OS compatible computers via LocalTalk connectors. The Ethernet connection supports Ethernet communication via an AUI-15 connection with transceiver. The 25-pin port supports serial communication with DOS/Windows computers. The push button switch is used to change the communication rates and protocols for only the 25-pin port. The SCSI connector is used for external hard drives to store downloaded font files; the SCSI connector is not used for SCSI printing directly from a Macintosh. This printer does support simultaneous communications.
