To change printer settings in ArcReader, click the ArcReader File menu and click Page Setup. The Page Setup dialog box opens. This dialog box contains options that allow you to change which printer you are using or the settings for that printer.

You can change the printer, the page size, and the page orientation on the printer. You can also choose whether or not to show the margins, or scale a map to fit a page.

When printing from layout view the entire published page is printed.

Printing in data view will print the currently displayed data frame at the current extent to the selected paper size. The printed data will be scaled to fit the page size you chose in the Page Setup dialog box.

You will not have the map elements, such as north arrow and scale bar, if you print from data view instead of layout view.
