Read the manual of your scanner and its driver.
See, that, what kind of communication it requires.
It may be inter process communication or socket communication(client-server).
So first you need to decide that, how your program and scanner can talk to each other.

Or it mey be as simple, that, you need to call a function of its driver, that HEY DUMB SCANNER, SCAN NOW.
And that poor scanner scans and writes a file on disk, so you can simply use that file.
