Yes. I need to learn Gimp so that I can print some photos of Tui’s paintings. I found that even the trial of Zoner Photo Pro is too limiting. I tried to print an image of a painting in GIMP but failed to get the size correct. Here is the image:
When I tried to print it, it only printed a portion of the image. Here is some relevant information about printing. I had learned this when I was working on the CDI project at UVM but forgot.

OK. I did everything right except I didn’t change the size of the image and paper source in the printer preferences.
Resolution
Digital images comprise of a grid of square elements of varying colors, called pixels. Each image has a pixel size, such as 900 pixels wide by 600 pixels high. But pixels don’t have a set size in physical space. To set up an image for printing, we use a value called resolution, defined as the ratio between an image’s size in pixels and its physical size (usually in inches) when it is printed on paper. Most file formats (but not all) can save this value, which is expressed as ppi — pixels per inch. When printing a file, the resolution value determines the size the image will have on paper, and as a result, the physical size of the pixels. The same 900×600 pixel image may be printed as a small 3×2″ card with barely noticeable pixels — or as a large poster with large, chunky pixels. Images imported from cameras and mobile devices tend to have a resolution value attached to the file. The value is usually 72 or 96ppi. It is important to realize that this value is arbitrary and was chosen for historic reasons. You can always change the resolution value inside GIMP — this has no effect on the actual image pixels. Furthermore, for uses such as displaying images on line, on mobile devices, television or video games — in short, any use that is not print — the resolution value is meaningless and is ignored, and instead the image is usually displayed so that each image pixel conforms to one screen pixel.
