Hi

I'm looking for a way to batch print at set of flags in GIMP.

All flags (jpg) are in the same folder. Flags have different aspect ratios, but
I need to print them all with same preset width, maintaining aspect radio.
Hence, the height will differ.

Also, I need to print the flags on both side side of the paper ("ala duplex"),
but since some flags are not symmetrical, I need to print both sides of the flag
next to each other lige this: [mirrored][original]

I have attached some flags as examples. How do I setup GIMP to do this?

Resize and flip might be the easiest part using a Gimp plugin BIMP.

If using Windows see: https://alessandrofrancesconi.it/projects/bimp/ Linux - I might be able to help. OSX - who knows.

Run on your set of images twice. First time resize and rename to a new set. Second time resize, flip and rename to second new set. see: screenshot (1)

Setting up a page. You need to keep everything symmetrical. Because printers often impose a margin and scale an image to suit, I advise (1) Use one of the Gimp standard page sizes (2) crop that down to a slightly smaller size. Use pixels as units, and a size easily divisible. You can use a grid sized to suit. Image -> Configure Grid and set View -> Snap to Grid. Save as a Gimp .xcf and the grid settings / guides etc are saved with the image.

Then create a front using one set and a reverse using the second set. screenshot (2)

Printing from Gimp in Windows is horrible. Plenty reports of problems. Often best to use some other application. However. Make sure the File -> Page Setup has sensible values for margins. Make sure the image is pulled to the top-left corner (remember it is smaller than the paper size) so that printing starts at 0,0 screenshot (3)

Plenty things can go wrong, best of luck.

Thank you very much for the detailed answer. I'm very grateful, and with try to
follow your guidens and hope the printer (win10) will corporate with me :)

Apologies, That reverse side image should go to to top right corner not the top left as shown in the screenshot.

Windows 10, check the software that comes with the printer. See if you can print 'centered' then you will get a match. Need that for automatic duplex printing where the printer flips the paper.

Other applications for printing? Export your images as png. XnViewMP is free and good.
