You shouldn't top-post, that's for email. The effective resolution of
photo paper is around 200-250 ppi. By keeping the resolution of your
digital images above 300 ppi you ensure that no pixilation will be
detectable on your final output.

For digital printing on an inkjet or laser printer connected to a
computer the resolution recommendations have little to do with the
paper. It has everything to do with the print engines used by output
devices. And in fact, for inkjet printing generally a 150 ppi image is
more than enough for a photographic output

With real printing, on a printing press, the paper does play a small
role (because of dot gain, which is explained last).

Note, I don't disagree with anything you wrote. I was talking about
photographic paper, hypothetically the best possible output. Most
people are shocked to find out that the effective resolution of color
photo paper is only around 200-250 ppi, after all negs are an order of
magnitude higher resolution. My personal policy is to keep everything
above 300 ppi so I know no matter how I output it, the digital nature of
it won't be detectable.

Re. inkjets. I've been forced to print inkjet at 150 ppi or so, and the
result was ok, but on close examination you could tell. I'd say keep it
above 200 ppi if you can.

I don't get published much in mags, so I'll let all of that stand.
Sounded good to me.
