Setting Paper Dimensions (Custom Size)
You can specify the height and width of paper when its size cannot be selected from the Page Size . Such a
paper size is called "custom size."
There are two ways of setting a user-defined paper, setting the paper from Size Options... on the Page
Setup tab and setting the paper from Custom Size of Page Size .
If you will be using a user-defined paper repeatedly, setting it from Size Options... is convenient because it
becomes registered to Page Size and can be selected any time after that.
If you want to use a user-defined paper temporarily, setting it from Custom Size is suitable.
The procedure for specifying a custom size is as follows:
Setting from Paper Size Options
1. Open the printer driver setup window
2. Click Size Options... on the Page Setup tab
The Paper Size Options dialog box opens.
