[Gimp-user] GIMP keeps reducing the paper size

[Andrea]

Hi,

I'm using GIMP 2.6.4 (same happens in 2.6.3)

I want to print a photo (on a photo paper 4x6), to a HP Officeject j6410, via CUPS 1.3.9.

1) open the picture
2) File->Page Setup
3) Format for: I select the printer
4) Paper size: I select "Photo or 4x6 inch index card"
5) the correct size appears: 101.6x152.4 mm
6) close the dialog.

Now, each time I reopen the Page Setup and click APPLY I see a different size

1st) 101.6 x 152.4
2nd) 53.6 x 35.8
3rd) 19 x 12.6
4th) 6.7 x 4.5
5th) 2.4 x 1.6
.....

On top of that, the "Format for" field has been reverted to "Any printer"

If I try to print the picture, (File -> Print) I see exactly those sizes (which I cannot change).
Actually I see the "next" size in the list.

Does anybody have a clue?
