It's just like you built a boat in your basement, and now you can't get it outside.
Open the Qimage HELP FILE and reset Printer.
Now click on Print Page setup (Upper right corner where there are 3 buttons; the left of the three)

Set the paper type and size. Set Quality, and set color controls to off (Assuming you use a printer profile)

Close that Printer page setup (The driver)

Now Qimage will show you the printable area of the A3 page.  411.9mm x 290.1mm
That's what your printer allows for maximum print size on A3.

Now, what size print do you want?
Forget original size. We can deal with when one would need that later.

Assuming you want the largest print possible, you open Print properties, Crop scissor on, and click Fit to page.

Ok, let's stop here and see if you are up to speed, and you can tell me what EXACTLY you want to make.

Fred

If I choose any other paper, no problem.... I simply select Borderless, and then add a 35mm border in white to my print. Fit to page with crop on...

Something about that paper choice in the driver that throws all size settings to the wind.
Perhaps your book or a call to Canon might shed some light.

Maybe someone you or anyone who has the physical printer can make a print and actually measure it.

Fred

Hi John.
I wake up very early here in the US. Otherwise Terry, who resides in the UK, will wake me with a text message to my cell phone.
So I might as well wake early.

It isn't so much the imposed 35mm margin as much as it is the change of size. The A3 changes to Letter size. Then you can override and select A3 again and that page size is not even close to A3.
Then I looked for User defined page, and it appears that Canon has removed that option. I thought we could sneak around through the back door.

Ok if I can help in any way, just holler.

Fred

Thanks Fred and Terry for all your suggestions and your patience. You really are Superheroes!!!

The paper I'm using is Innova FibaPrint White Matt. Using Canon's "Fine Art" paper setting, it produces excellent monochrome prints with good detail in the shadows but imposes that wretched 35mm margin. I changed the paper type to Matte Photo Paper and that's removed the 35mm margin, but the gradation is nowhere near as good, with less dense full black and, even worse, muddy shadows with no detail. (I'm spoiled, I suppose, by those days long ago in a "real" darkroom with Ilfobrom and the like!).

I'm now going to experiment with different profiles for this paper and, maybe, look for a matt paper that performs better with this printer at that setting. Hot foot to Fotospeed's website!

I'll let you know of the outcome. I'm still confused by QI's print size settings though, and I have watched the video! 

Incidentally Fred, how do I get to the dialog box that you posted above (called Image 131.jpg)? I can't find any buttons or shortcuts that show me that.

That is located in the Qimage Ultimate Page Editor with the Size Location tab clicked.


As Terry is trying to say, and I touched on earlier, mentioning that Original Size is only used on rare occasions.

Qimage is very simple and brilliant to use especially when making a print to a certain size.
John, the only time it becomes a mystery is when the user has spent a lot of time in Gulag Photo Shop, and has been approaching printing from the wrong direction.

Just tell us, Terry or me, what size print you want to make, preferably from a file that you have not fooled with regarding size or shape.
In under 30 seconds your printer will be running.

I use original size when I want to print a TARGET image that has a specific ppi and a specific size for that ppi.
