Apple Power Macintosh 4400 - Manual (Page 113)

m Drag special software items out of the System Folder or remove them
permanently. (The special software may be in the Control Panels or
Extensions folder inside the System Folder.) If the computer performs
better when the software is removed, contact the software’s manufacturer
for information or an upgrade.
Hint: If you have more than one special software item, drag all the special
items out of the Control Panels and Extensions folders. Then return them
one at a time, restarting and checking your computer’s performance each
time until you identify the one that is causing problems.
If you still do not notice an improvement, follow the instructions in
“Installing or Reinstalling System Software” later in this chapter to reinstall
system software on your startup hard disk.
Solving printer problems
The following suggestions should work for all printers:
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. If it doesn’t, click to put a checkmark beside it, and
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 active.
m Next, turn off the computer and printer and check the printer cable
connections.
m If neither of these suggestions solves the problem, reinstall your printer
driver. If your printer is an older model, do not use the driver that came
with it. Instead, use the updated printer drivers provided on the system
software CD-ROM that came with your Power Macintosh. These drivers
are created especially for use with the Power Macintosh.
