Installing Options
If you purchased any printer options, such as extra memory or
emulations, install these now. If installation instructions are
included with the option, follow those, and be sure to check for
additional instructions in chapter 8, “Printer Options.” Then return
to chapter 3, “Connecting the Printer,” to finish setting up your
printer.
