Tom,
I am trying to replicate your instructions.
I get 2 prints on the page (defined as 5.25 wide and 10.50 tall in size)
My prints are 5.02 x 5.13 each.
That is defined by you telling Qimage to print one column and two rows of prints.

I check the Full page editor for placement, and I show 0.12 inches all the way around.
The layout placement is Template Centered because you selected Columns and Rows to define the page.

Please read over what I did and tell me what I have that is different from your setup.
I attached some screen snaps to show the preview panel, and the Full Page Editor with all the margins showing with either image selected.
You get 0.12 on all sides.
Check your printer driver to see if you set anything in there that would alter Qimage's location settings.

Hi Tom,
Where did you try to do this?
You can't do it in the Full Page Editor but you can in the menu Page Formatting\Page Margins. You can even put in negative values.
This technique is used to correct small, but consistent, transport registration errors, when expansion is turned off for borderless printing.
Terry.
