I already opened up a bug report on this:
https://bugs.launchpad.net/hplip/+bug/1415121, if anyone's interested.

What I wrote already in the prior email makes it clear this is a 1200dpi
scanner.
"4 pixels per dot" would correspond to 3 colors + a B/W bit for each
dot-- what would be required for color scanning at 1200dpi. "Pixel" is
a rather slippery term. Perhaps the tech should have said "sensel". But
this was tier-one tech support after all, not a developer I was talking
with. And she had to look up that much.

"4 pixels per dot" is a meaningless statement. A dot is a pixel. You
would have to ask the hplip guys if they can get 1200 dpi out of this
scanner.

According to specifications published by HP, this scanner's hardware and
optical resolution is 1200x1200 dpi. I just called HP tech support to
confirm this and was told this is correct and that, further, there
are "4
pixels per dot", meaning that the scanner handles both color and B/W
at that
resolution. So I don't know why scanimage would report that 300dpi
is the
maximum resolution.
