Hi mitch308
What operating system are you using? The image created is a 600dpi image. Printing in 600dpi with no scaling (100%) should give you the true and correct size.
I’m using a mac myself, and using preview, I convert to pdf and print that pdf.
On Windows you could open image in Paint and print from there?
I’ll find some time to make some guides. If others have input on how to print in actual size or tricks how to do it, please share
