Menu Bar

 

1. Apply Settings to the Printer
   Applies the settings to the printer.


2. Save Settings in Command File
   Saves the specified settings in a command file. The file extension is ".bin".
   The saved command file can be used with the mass storage mode to apply the settings to a printer.
   • If the [Disable these settings] check box is selected, the settings in that tab are not saved.

   • The following information is not saved with the command file:

     • Node name
     • IP address, subnet mask and default gateway (when the IP address is set to [STATIC])
   • The saved communication settings commands are intended to be used only for applying settings to a printer. To apply the settings to the printer using this command file, use the mass storage mode.
   • Saved command files contain authentication keys and passwords. Take necessary measures to protect saved command files, such as saving them in a location that cannot be accessed by other users.
   • Do not send command files to a different printer model.
3. Install Certificates
   Some network authentication methods may require a certificate.
   Install a certificate on the connected printer or save a certificate as a command file that can be distributed to the same model printers.


4. Import

    

   • Import from the current computer wireless settings (TD-4550DNWB)

     Imports the settings from the computer.

     • When importing the computer's wireless settings, administrator privileges for the computer are needed.
     • Only personal security authentication settings (open system, public key authentication and WPA/WPA2-PSK) can be imported. Enterprise security authentication (such as EAP-FAST), WPA2-PSK (TKIP) and WPA-PSK (AES) settings cannot be imported.
     • If multiple wireless LANs are enabled for the computer you use, the first wireless settings (only personal settings) that are detected will be considered for the import data.
     • Only the settings (communication mode, SSID, authentication method, encryption mode and authentication key) from the [Wireless LAN] tab - [Wireless Settings] can be imported.
   • Select a Profile to import

     Imports the exported file and applies the settings to the printer.
     Click [Browse] and select the file you want to import. The settings in the selected file appear in the settings display/change area.

     • All settings, such as wireless settings or TCP/IP settings, can be imported, except for node names.

     • Only profiles that are compatible with the selected printer can be imported.

     • If the imported profile’s IP address is set to [STATIC], change the IP address of the imported profile as necessary, so that it does not duplicate the IP address of an existing configured printer on the network.
5. Export

   Saves the current settings in a file.

   • If the [Disable these settings] check box is selected, the settings in that tab are not saved.

   • Exported files are not encrypted.

6. Automatically restart the printer after applying new settings

   If this check box is selected, the printer automatically restarts after communication settings are applied.

   If this check box is cleared, you must restart the printer manually.

   When configuring multiple printers, you can reduce the time needed to change settings by clearing this check box. In this case, we recommend selecting this check box when configuring the first printer so that you can confirm that each setting is operating as intended.

7. Automatically detects the connected printer, and retrieves the current settings

   If this check box is selected and a printer is connected to the computer, the printer is automatically detected and the printer’s current settings are displayed in [Current Status].

   If the connected printer is different from the one shown in the [Printer] drop-down list, the settings available on all tabs change to match the connected printer.

   For details, see Menu Bar.

3. Click [Apply].
   The same settings that were applied to the first printer are applied to the second printer.

   (TD-4550DNWB)
   We recommend selecting the [Automatically restart the printer after applying new settings] check box when configuring the first printer so that you can confirm that the printer can be correctly connected to the wireless router/access point with the new settings.
   For details, see Menu Bar.

4. Repeat steps 1 - 3 for all printers whose settings you want to change.
   • If the IP address is set to [STATIC], the printer’s IP address will also be changed to the same address as the first printer. Change the IP address if needed.
   • To save the current settings in a file, click [File] - [Export].
     The same settings can be applied to another printer by clicking [File] - [Import], then selecting the exported settings file. For details, see Menu Bar.
