@BartHays This could potentially be a usable work around I will need to try it across both OS's. - Although I still think ill fall victim to the drawings being unaligned on the design layer.
@Jonathan Pickup Unfortunately I have had absolutely no luck trying to create a custom page size on a Windows PC. More frustratingly I presumed that the 'Non-print area' would be printer defined but even after installing the same driver on both machines I am still having the same issue.
