This is wrong, right? There is no such thing as a genuine check outside of conventions for repudiation(out of order check numbers, not on my check paper). Whether it came from the checkbook my bank sent, or out of my printer, it is just as good. Legally, writing it on a napkin would probably work, but draw lots of scrutiny becuase it looks suspicious and can't be processed automatically.
