Note any differences. Possible problems include:
• The WAP filters hardware addresses (MAC addresses). See Configuring wireless
security settings.
• One of these settings in the printer might be incorrect: Communication mode,
Network Name (SSID), Channel (Ad hoc networks only), Authentication Type,
Encryption. See Configuring wireless communication options.

default settings (see Administer the printer) and reinstall the printer software
(see Configuring the printer (Windows) or Configuring the printer (Mac OS)).

Printer takes a long time to print
Check the system configuration
Make sure the computer meets the minimum system requirements for the printer.
See Printer specifications.
Check the port setting
The port setting configuration in your system might not be set to ECP.
See the documentation that came with the computer for information on how to change the
port setting, or contact the computer manufacturer.
Check the printer software settings
The printer prints slower when Best or Maximum dpi is selected as the print quality.
To increase the print speed, select different print settings in the printer driver. See
Changing print settings.
Check for radio interference
If the printer is connected using wireless communication and is printing slowly, then the
radio signal might be weak. See Reducing interference in a wireless network.
