Hi, I suspect this is a really basic question, so basic that the answer is not readily available!

I am making a poster for A3 size printing at a printer.

My Publisher 2003 is set up for A4 as standard. The printer said he could not print my file on A3 and that it had to be scaled up to A3 or something.

I have looked around in books and online and cannot find how to do it.

None of my home printers print larger than A4 so I hope that is not a problem in setting up the page for A3 in Publisher.

Any guidance will be gratefully received.

Thanks
