Can't print an image at more than 100% size

[Teo]

NO IDEA WHAT PACKAGE THIS IS: I just chose "cups" because it's related to printing

- open an image in the Image Viewer
- do image/print
- go to the "image settings" tab
- try to amplify the image

=> YOU CAN'T!!!!!
The maximum is always 100%. Why? That's stupid. For MOST images moreover (any image that was not scanned), there is no sensible notion of a physical size (the dpi resolution is completely arbitrary), so the notion of 100% is totally random.
Not being able to increase size to more than 100% is almost as huge as not being able to print. It's among the most nonsense limits I've ever seen.

Maybe it's somewhere else, perhaps in "advanced", but it should be possible from this very tab. Wher you can reduce size, you must also be able to increase it.

Oh my f****ng god. There's a "page setup" tab where you can set a scaling for the page that can be both below and above 100%, but then when you go to the image settings which is where you see the preview, the preview does not take into account the page scale, so what you see is not even close to what you are going to print (unless page scale is 100%).
So you can print with increased size but you have to become insane calculating what the hell the result will be (basically by printing and error: huge waste of paper. Earth, say thanks to Ubuntu).

[Teo (teo1978)]

And the "page setup" settings are remembered, so if you set it to other than 100%, you will almost certainly forget about it. Next time you print you won't even look at the page setup page, and you'll wonder why you get unexpected print scalings. Demential.

Scaling both below and above 100% must be in the "image settings" tab, there's no other reasonable option.

This is a problem of the print dialog, which is part of GTK, not of CUPS. Moving ...

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.
