A method of previewing an electronic document using display device forming
part of a computer system intended for printing is disclosed. An
electronic document having at least one printable page is provided and
formed into a print preview representation of at a default preview size. A
grid is formed and associated with the representation, the grid having
cells corresponding to individual pages at said default preview size. The
representation is displayed on the display device with the grid overlying
said representation. Using at least one input device of the computer
system, a part of the arid is selected. The selected part is moved to
cause a change in size of the grid such that an aspect ratio of said cells
formed by said grid remains constant. On de-selecting the grid, a further
print preview representation of the page is formed at a preview size
corresponding to that of the change in the grid.
