m Use the Memory control panel to turn off virtual memory. For more
information on virtual memory, see the “Memory” topic of Macintosh
Guide, available in the Guide (h) menu.
If you still do not notice an improvement, you may want to reinstall system
software on your startup hard disk. See Chapter 7, “Reinstalling Your
Computer’s Software,” for instructions.
If you typically use several application programs at the same time, your
computer’s performance will increase if you install more RAM (random-
access memory). See Appendix B, “Installing Additional Memory.”
Solving printer problems
The following suggestions should work for all printers. (Note: Also refer to
the manual that came with the printer.)
m Make sure that the printer driver for your printer is turned on in the
Extensions Manager control panel (in the Control Panels folder in the
Apple [K] menu). To find out the name of the printer driver—for example,
LaserWriter—refer to the documentation that came with your printer. The
printer driver should appear in the Extensions list and have a checkmark
beside it. (Click to put a checkmark beside it, and then restart your
computer.)
m Check your printer settings in the Chooser (in the Apple [K] menu),
making sure you have selected the correct printer. If you are using a printer
that is shared by other computer users (a printer on a local network), make
sure that AppleTalk (in the lower-right corner of the Chooser) is active. If
you are using your own printer (a serial printer connected to your
computer), make sure that AppleTalk is inactive.
m Turn off the computer and printer and check the printer cable connections.
m If none of these suggestions solves the problem, you may need to reinstall
the printer driver that came with your printer. Refer to the manual that
came with your printer.
