Apple Color StyleWriter 4500 - Manual (Page 18)

Special information for PowerBook owners
PowerBook computers that have internal modems may require special setups.
What you do depends on whether the Powerbook has one or two serial ports
on its back panel.
Note: This information is for PowerBook users who connect the printer
directly to their computer with a serial cable.
PowerBook computers with one serial port
Some PowerBook computers have a single serial port identified by a
combination printer/modem icon (
[/W). If an internal modem is installed on
one of these PowerBook computers, the serial port may be in use even though
it looks available. When you plug in the Color StyleWriter 4500, the
PowerBook may not be able to communicate with the printer.
To make the port available for printing, make sure the serial port setting is
Normal or External. To check the setting, open the PowerBook, PowerBook
Setup, or Express Modem control panel. (If you have another kind of internal
modem, you may have a different control panel. The control panel and the
setting you use depend on which PowerBook you have and which internal
modem you have.) If you have a PowerBook Express Modem, it is best to
leave the serial port setting as Normal or External unless the modem
programs you use require another setting for compatibility reasons.
PowerBook computers with two serial ports
Even when a PowerBook has two serial ports, if it also has an internal
modem, the modem port (
W) may look available but actually be in use. If the
printer port (
[) is available, connect the Color StyleWriter 4500 to it. If the
printer port is unavailable and you must use the modem port, make sure the
modem serial port setting is Normal or External. To check the setting, open
the PowerBook, PowerBook Setup, or Express Modem control panel. (If you
have another kind of internal modem, you may have a different control panel.
The control panel and the setting you use depend on which modem and
system software version you have.) If you have a PowerBook Express Modem,
it is best to leave the serial port setting as Normal or External.
For more information, see the instructions that came with your PowerBook.
