Just as many photocopy machines have a reduce/enlarge feature, Microsoft Word offers different ways to scale a document for printing, enabling you to avoid adjusting margins or line breaks.
Note When you scale a document for printing, the changes only occur when you print. Word does not change the settings in the document itself.
For example, you can specify that a B4-size document prints on A4-size paper.
Tip
This procedure scales your document for this printing session only. To scale your documents this way for all printing sessions, click Options on the Tools menu, and then click the Print tab. Select the Allow A4/Letter paper resizing check box.
