Java Runtime Environment Restrictions

JRE6.0

If you are using Java Runtime Environment version 1.6.0-1.6.0_03, and the [Temporary Internet Files] is enabled, Web Printing Tool might not start properly. If this is the case, delete the temporary files, and then disable "Temporary Internet Files" in the Java Control Panel. To open the Java control panel, click [Control Panel] on the [Start] menu, and then click [Java].

JRE7.0

In Java Runtime Environment version 1.7 or later, you cannot launch Web Printing Tool in the standard setting. Change the setting using the following procedure:

  1. Open the Java control panel.

    • Windows OS

      Click [Control Panel] on the [Start] menu, and then click [Java].

    • Mac OS

      Click [Java] in the [System Preferences].

  2. Select [Security] tab, and then click [Edit Site List].

  3. Click [Add].

  4. Click in the empty field under [Location], and then enter the machine's IP address.

  5. Click [OK].

  6. Click [Continue] on the Security Warning dialog.

    The printer's IP address is added to the exception site list and it becomes possible to launch Web Printing Tool.

Note

  • If you are using a proxy server, change the Web browser settings. Contact your administrator for information about the settings.

  • We recommend using Web Printing Tool in the same network.

  • You cannot access to the machine from outside the firewall.

  • When using the machine under DHCP, the IP address may be automatically changed by the DHCP server settings. Enable DDNS setting on the machine, and then connect using the machine's host name.

  • Alternatively, specify a static IP address to the DHCP server.

  • When using a host name under Windows Server 2003/2003 R2/2008/2008 R2/2012/2012 R2 under the IPv6 protocol, perform host name resolution using an external DNS server. The host file cannot be used.
