I have created a poster but need it to be printed to a PDF using a certain dimension for the printers to use.

The poster will be printed at 300cm wide by 450cm in height. But no matter how I print to PDF using PDFCreator it always defaults back to A4.

I was able to print to a JPG file but the quality of the image is not very good even when I change the settings in Publisher 2002 to print images at 100%. Printing to a PDF gives a better quality but the dimensions are not exactly how the printers need it as they will only print from the file and will not and can not alter it.

Can anyone advise how I do this correctly as I just can not get my head around it at all.

Thank you
