|You can print your own checks as long as they conform to certain
|specifications.  According to my understanding, a document that
|conforms to a specific legal definition qualifies as a check.  This
|document MUST include 5 pieces of information: the name of the bank
|upon which it is drawn, the name of the payee, the date, the signature
|of the account holder, and the amount of the check.  Notice that the
|account number is not among the requirements.  Theoretically, you can
|write a check on a napkin, and the bank is legally obligated to honor
|it.
|
|I do not know if this applies in all states, or even if it is an
|antiquated standard that has been superceded in recent years.  But I
|do know that, on a practical level, banks will give you a hard time if
|you try to present a check that is not pre-printed.  (Once I had to
|deposit a check that was a photocopy, and the bank whined about it,
|but they ultimately honored it -- and it was good.)

My bank charges a fee for checks written on "non-standard forms".
Presumably this is to discourage checks that cannot be processed by
automation.  Your bank may have a similar requirement in the fine
print.  I assume they make a special case for those gigantic checks
used for charity publicity.
