GIMP shrinking image/layer when I import to a new/different image

Sad GIMP shrinking image/layer when I import to a new/different image
I am new to using GIMP. I am trying to use it to design button badges on my new laptop. I have photoshop on my old laptop and have lots of psd files that I have been trying to use with GIMP.

I am finding that GIMP is shrinking my images when I import them to different images and when I come to print them on A4 they are smaller than they should be, and so useless to me in making my badges...

Printing the original image from GIMP gives me it in it's intended size though. How can I stop this from happening?

It happend when I import into an A4 - as I need to fit approximately 40 badge images per sheet.

Any help would be much appreciated, as I now intend to use GIMP full time of I can overcome this obstacle.

Thanks,

Gem

The only important "measure" of a bitmap image is its size in pixels, and you'll find that Gimp isn't changing that. There may be a discrepancy in the assumed dots per inch of the image but this can be changed (in Gimp's print dialog you can change the DPI setting on the image on the fly).

These are PSD files I'm working with.

The layer I want to add is 394 x 394 pixels, when I add it to an A4 template - it still says that as a layer it is 394 x 394. But when I print these images (the single 394 pixel and the a4 template with the same image added) the latter shrinks the image by a few millimetres.

In the print box in image settings in the print dialogue box says the original image is 300 by 300 dpi/in and for the A4 sheet it is 344.259 - and it will not let me lower this to less than 318.909, and it only lets me do this if I select 'ignore page margins'

Am I missing a trick here?

RE: GIMP shrinking image/layer when I import to a new/different image
So, you insert your 394x394 layers into a bigger canvas/template? How big is that one? I think the real explanation is that your canvas at 300PPI is too big to fit the printable area as determined by the printer driver installed in your new PC so it gets scaled down and so do its contents, and Gimp would have little responsibility in that.

Solutions:

1) find a way for the print driver to define/accept a larger printable area
2) print the image using another utility (Windows Image Viewer or else)
3) use a smaller canvas that fits the printable area at 300PPI.
