If you mean pixels per inch, 300 should indeed be fine. However, if you
mean dots per inch, then 300 dots per inch would not be very good at all.
Do not confuse dots per inch with pixels per inch. It takes at least 3 dots
per inch to make a pixel. Printer manufacturere usually quote dots per inch
because that is indeed how printers work.

I suspect this poster has simply misused the terminology. I don't think
Photoshop uses dot per inch.

I would suspect he is referring to pixels per inch within Photoshop.

He might want to try not using "high speed" and see if that works.

Peter,

My reply was actually to Jim's comment:

not to yours, but if you wish to split hairs, you actually did state
dots per inch in your response see quote below: (dpi = dots per inch).

The proper abbreviation for pixels per inch is ppi.
