Welcome!
First of all, Qimage reports the read of the print driver.
It appears that you have not set the borderless option to ON in your print driver. After selecting the paper size (4 x 6) and borderless, Qimage will show the results from the driver, and it will show 4 x 6 as the available space on the paper for printing.
It would also be wise to have the crop scissors on in case there's a need to fill.
Really, the simple way, the best quality way, would have been to set the driver as 'above', set the print size to 4 x 6, crop scissors on, put the image in the queue, (add image).
Then open the Full Page Editor screen for print cropping, and (make sure you are in the cropping tab) using the zoom bar on the right, and the mouse (hand) upper right small image, slide the image around in the frame to where you want the crop, zoom in or out to set the image exactly the way you want it, and print it!
Hope you will try this a few times.
menu showing zero for borders
Borders are what you add to your print when you want to fancy it up!
Margins will be zero after you set the driver to borderless.
e set to OFF unless using a dedicated ICC profile.
You should have or you should now, find and download the real printer/paper profiles from the printer manufacturer or paper manufacturer and use them.
If you don't have any, then I suggest you use the "Let Printer Manage color" option in Qimage.
e) Is correct, but that is used when you "do" have a proper printer profile, and when that driver setting is recommended by the creator of the profile.
Last but certainly not least, is asking you to take 10 minutes to read and get a handle on profiles by reading Mike's articles posted right here on theis forum.
