There are a couple of ways to do this - You could use a table with four
cells, or you could simply print four pages to a sheet - see

Hi Mike,

Here are two ways:

- Go to Tools > Letters & Mailings > Envelopes & Labels, on the Labels tab.
In the Options, select Avery stock 5845. Click the New Document button; this
creates a one-page document containing a full-page 2x2 table. (If you can't
see the cells, click Table > Show Gridlines.) Create your insert in the
first cell. Then copy that cell to the clipboard, select the whole table,
and paste to replicate it to all four cells. Alternatively, bookmark the
first cell and insert Ref fields in the other cells that refer to the
bookmark. Print that page in the ordinary way.

- Create the insert on a full-size sheet, using fonts and graphics that are
twice as big as the desired final size. In the Print dialog, choose 4 pages
per sheet at the lower right, and in the Pages box type
  1,1,1,1
The page will be scaled to half-size and printed four times on the sheet.
