I did not take that step and the above process finally solved a long-time nagging problem with this printer being used on multiple PCs.
NOTE 2: You should not have to return to the PC that I am calling "the PC where the Printer was first installed as a Wireless Printer." If you cannot locate that PC, I think you could UNinstall the Epson Drivers and Utilities from all your PCs, download the latest Driver and Utility Combo pack, and start over with a new install.
Attention Mac OS X 10.6 and 10.7 Users: Newer drivers may be available directly from. Double-click the installer icon to begin the installation.

It seems that going to the Printer and Options Information function may reacquaint the PC with having the Auto Duplexer available. This file contains the Epson Artisan 810 Printer Driver v8.11. This may even be required every time you want 'Auto' 2-sided printing on the PC you are USING. NOTE: You may have to "reaffirm" that the Auto Duplexer Installed is checked on every other PC by going to the Printing Preferences Maintenance tab then selecting Printer and Options Information.

Locate the PC on your network where you find that you can select Auto Duplexer Installed by going to Printing Preferences, the Maintenance tab, and clicking Printer and Options Information. If your document fails to print on both sides of the page, follow the instructions below, particularly if the 'Auto' option is grayed out and/or the checkbox for Auto Duplexer Installed is grayed out (whether checked or not), then: (If 'Auto' is grayed out, still continue through these instructions) Go to the Page Layout tab of Printing Preferences and select the 'Auto' radio button for 2-sided Printing if available Click OK to exit the Printer and Options Information box (That checkbox may be grayed out and may be checked or not checked, but continue through these instructions) Ensure Auto Duplexer Installed is checked for 2-sided Printing Settings In Printing Preferences, on the Maintenance tab, click Printer and Options Information Situation: When 'Auto' radio button for 2-sided printing is grayed out in Page Layout tab of Printing Preferences:
This process solved my grayed-out "Auto" duplex selection on Windows 7 and on Windows 8 PCs. These steps did not seem to be required for USB connections to the printer, and WIRED Network printing was not tested. To achieve Wireless Network printing to the Epson Artisan 810 on both sides of the page (duplex), try the steps below. Situation: 'Auto' radio button for 2-sided printing is grayed out for Epson Artisan 810.
