■ When you connect multiple printers using the USB interface, use the external
USB hub.
When you connect multiple printers using the USB interface, use the external USB hub and then
install the printer driver. (when using Windows 98, install the printer driver each time you connect
the printer.)
For more details, please refer to the Driver and Utility Guide for Windows Users or the Driver and
Utility Guide for Macintosh Users in the Reference Guide (CD-ROM), depending on the computer
system you are using.
■ Disconnect the USB interface cable on the side of the computer or USB hub.
When you disconnect the USB interface cable while the printer and computer are turned on,
always disconnect on the side of the computer or USB hub.
■ Do not turn the printer off while the printer is executing a print job. This could
cause a malfunction in the printer.
