Nice catch - I overlooked that item:
23. W2 Form Printing, Quarterly 941 Printing or 1099 Form Printing are not listed on menu in Sage 100 ERP version 2013?
New installations of Sage 100 ERP will not have the 3 menu tasks listed. To enable these tasks, from the toolbar menu click File > Run and type the utility name *unhidetaxforms
When these menu options are unhidden, these installations will get the same warning message to say that 'starting in 2014no longer supported'.
Note: After the 2013 Tax Filing Year, Sage will no longer be providing standard W-2, 1099 and 941 form changes in the standard Sage 100 product. You will be able to use eFiling and Reporting feature, which allows you to either print W-2, 1099 and 941 forms directly to your printer and/or eFile directly to applicable tax agency through Aatrix.
