How to make a booklet with page numbers with word2003?

This does not require other software, and word can fully meet your requirements.

In the page setup, the multi-page option of the page number range under the margin label is set to book folding, and the rest are the same as ordinary documents, so there is no need to use columns to solve it (in this state, one page has been divided into two pages). You can set different home pages, different parity pages, and different headers and footers in the layout. As for the page numbers in different formats, you need section break, starting from the text and adding section break before the text of the first page. When you set the page number, you need to break the link between the two headers and footers, and you don't need a special field code to complete it.

Note: You can't see the effect in editing status and print preview status, and you need to print before you can see the effect. If you are not sure, you can use virtual printing first.
