What interface does a programmer see to a scanner?

If I write a program, and I want it to read a scanner, do I call
a driver that the scanner manufacturer installed?  If so,
what are the driver calls, and are they standardized across
scanners?  Where are they documented?

If I create a piece of hardware that acts as a scanner, and want
it to work with standard software, I assume that I want to write
a driver that emulates some other manufacturer's driver.  Who's
is most standard?

Thanks in advance.
