Summary:

The settings recommended for the printer control switch on the back of the Apple Daisywheel printer are as follows:

9600 baud 1, 2, 3 on XON/XOFF 4 on, 5 off No modem 6 on Space parity 7, 8 on

More Information:

Note that this printer is generally compatible with the Qume Sprint 11 and Qume LetterPro 20 printers. Depending on the type of Macintosh in use, the ImageWriter cable may or may not need modification for use with this printer, or an additional cable may be needed.

The following tables should help with selecting the proper ImageWriter cable modification for the hardware in use. Table 1 lists types of cables produced by Apple at present and/or in the past; Table 2 describes the necessary modification; and Table 3 gives the necessary pin hookups for constructing the needed cable or adapter.

Table 1
Cable Connector   Cable Connector Cable Type at Macintosh at Printer/Cable ———- ———— —————-

ImageWriter Male DB-9 Male RS-232 (from 512 to IW)

ImageWriter II Male DB-8 Male DB-8 (from Plus to IW II)

“Pigtail” adapter Male DB-8 Female DB-9 (from Plus to IW cable)

Note that a DB-8 connector is a round, 8-pin connector; a DB-9 is a 9-pin connector also known as RS-422; and an RS-232 is a standard 25-pin serial connector.

In general, the ports on the Macintosh and ImageWriter are always female. Hence the cable connectors are always male, except with the “pigtail” and other adapters. The port on the Apple Daisywheel printer is also female.

Table 2
Type of Cable Macintosh Type Modification Needed ——— —- ——————-

512, 512E IW No modification needed.

512, 512E IW II It is easiest to construct a new cable (DB-9 male to RS-232 male).

Plus, SE IW Pigtail at Macintosh. Macintosh II

Plus, SE IW II Construct female DB-8 to male RS-232 Macintosh II adapter for use at printer end of ImageWriter cable.

The following pin connections need to be made when constructing a cable from scratch to connect a Macintosh with the Apple Daisywheel printer:
