A computer program operates a printer to insert tabs into a multipage document. The physical tabs are stored in one of printer's insert bins. A graphical user display shows a bank of tabs in a layout table. A tab is activated by specifying a page for the tab. Text and graphics may be entered on the tab or selected from templates for labels and style. A layout template stores data on the layout of one or more standard banks of tabs. The computer program automatically balances the number to tabs and automatically deletes unused blocks of tabs.
