Okular will only print at A4 size dispite changing paper size

Hi. I have Kubuntu 8.10, an Epson R265 printer and using Okular for PDF's. I only use A5 paper size and although i can select this in the Okular printer options, it always prints out at A4. Checking the Okular properties shows that Okular's print paper size is back at the A4 default. I have no problems with using 'Document Viewer', but would like to use Okular.

any help would be appreciated.
