Set the page size of your score to the proper
size. For example, 11 X 17 portrait. Use either Document > Page Format
for Score or the Page Layout tool. (See Page layout
or Page size.)
Choose Utilities > Update Layout.
Choose File > Page Setup. Choose
Landscape for the orientation, Letter for the page size and click OK.
Chose File > Print. In the dialog
box select Tile Pages. Specify the page range on which you’ll be printing.
Some printer drivers will allow you to specify the size of the component
pages (Letter or Legal) here. Other printer drivers store this information
in the Page Setup dialog box.
Type the amount of overlap you want in the
Tile Overlap text box. This amount is specified in the units you
have selected in the Measurement Units submenu of the Edit menu.
