My plug in has 11x14 as a standard paper size choice, therefore no need for choosing custom to define it. Are you saying you have no 11x14 standard choice or something else?
Did you know that you can drag the image in the preview pan to the (visual) position you want it (ie - top left, right, bottom, off center, center etc...)?
That's correct. I have no 11x14 as a standard size. I installed the Plug-in from the Canon Canada site on to an Intel Mac. Perhaps I should have installed the version on the CD (U.S.) and then try to to apply the Canada sourced download as an update. I didn't expect there to be that kind of difference so just went with the newer version.
I'll install the software from the CD onto another Mac and have a look. Then I can try the update to that Mac. If it looks right I'll uninstall and reinstall, first from CD then apply the Canadian update. Maybe Canon will have a U.S. update by the time I get to that.
And no, I did not think to try to drag the image in the preview pane, but I have not had an application where that would be needed yet. In my situation described above, the preview shows the image centered because it's expecting the 10x15" paper. Hence, the "trick". It's a good tip for other layout needs, thank you.
