### display_paper_size

Displays the current paper size in the main dialog box. If the paper size is A thru E or A4 thru A0, the dialog elements for the determination of the roll length are hidden and the current paper size is shown through static text. If the paper size is either a 24-inch or 36-inch roll, the paper size static message is hidden and the dialog elements for the roll length are shown. If roll feed is selected, the input focus of the main dialog is set on the roll length input box. The current paper size is then checked in the pop-up menu.
