Completely lost printing 360 covers

[Treyplay]

Was trying to follow a guide for printing 360 covers but I'm having zero luck. Downloaded a cover art from here for Import Tuner Challenge, the guide says if the cover is downloaded from here the sizing should be correct. However, all my prints come out way too small. Very confused about how to print the correct size. Tried both Gimp and Paint, Thanks!

1: First check the cover is 300DPI.

2: Make sure you have fit to page turned off and scaling at 100%.

Another suggestion is to check if  you have the option to show a preview of the print before it goes to the printer.  With my Canon MX922, I have the option to select "preview before print."  Using this can help you to notice if the print margins are out of wack before you waste paper and ink.
