N.Y. Senate Rules Rule 7, § 3: Printing

§ 3. Printing. Every bill immediately upon its introduction shall be

printed and placed on the bill files on the desks of the Senators, where

it shall remain for at least three calendar legislative days. All bills

reported favorably or for consideration, if reported with amendments,

and all bills amended in the Senate, shall be immediately printed,

except that any bill which is amended by restoring it to an earlier

form, shall not be required to be printed again, and thereafter the

printed number of the bill in the form to which it has been so restored

shall constitute the final form of such bill unless further amended.

Whenever a bill is amended and printed, a letter of the alphabet

starting with "A" shall be added to its number.
