You don't need to do any of that.  Your image is not 19.76 x 24.05: images don't have "size".  They have pixels.  Qimage can print any image at 54 x 24 with 18x24 panels.

I know this is my third time saying this so maybe the third time is the charm, but all you have to do is type in the print size you want at the top of the multi-panel UI.  In your video, the print size shows as 19.76 x 24.35 because that's the most recent print size you used.  Just type over that and type 24 x 54.  Then if you split it 1x3 (which makes the most sense to me if you want the final to be three 24x18 panels), you'll get three 24x18 panels.

And yes, you can print 18x24 panels on your 20 inch roll: Qimage will automatically turn the panels so the 18 inch side prints across the width.  It has to; it can't print 24 inches wide on a 20 inch roll.

The bottom line is if you followed my 4 steps I posted on September 23, it would work perfectly.  Not sure why, but you keep wanting to skip the step where I said Just enter 54x24 up top as the "Print Size".  Without that, Qimage has no idea what final size you want and it'll just assume you want that last-used 19.76 x 24.35 size.

I should also point out that the multi-panel print UI is super versatile so you can go at this from any angle.  You can give it the final print size and rows/cols like I've been instructing, BUT...

You can also specify the panel size and rows/cols and Qimage will automatically calculate the final print size.  Like this:

• As always, we make sure the crop button is enabled on the top left of the multi-panel UI
• Click on the "Panel Size" tab and specify a panel size of 24 x 18 by entering 24 in width and 18 in height
• Click on the "Cols/Rows" tab and specify 1 column and 3 rows
• Click "Generate"

Since Qimage knows you want 1x3 panels of 24x18, it'll automatically calculate the final size of 24x54 and you'll get your three 24x18 panels.

The key is, there are three parameters involved when making any multi-panel print: (1) size of each panel, (2) number of panels in rows/cols, and (3) the final print size.  The UI is set up so all you have to do is specify any TWO of those three parameters and it can (and will) calculate the third.

You got it right with this one and if you had clicked "OK" to accept those three panels pictured by the green boxes (you cut off the "OK" and "Cancel" buttons but they are there past the bottom of your screen shot), you would have gotten the three panels in the queue:



Did you click "OK" on that dialog?  If so, it would have added the three panels to the job.  It looks like you had been fooling around and added multiple copies of the image before doing the multi-panel print so the multiple panels could have been on subsequent pages.

And again, there was no need to resize the image in another program.
