Alfred....You are confusing image resolution - 301ppi- with printer
resolution - 1440dpi.
Your image is correct at 12 x 18 at 301ppi...there is no need to
resample, you just need to select either 1440 or 2880 as the printer
resolution and the driver will take care of it for you. I would suggest
1440 is quite enough, it takes forever at 2880 with little if any
discernable improvement in image quality.
