question concerning new paperv dollars entering economy

does the Bureau of Engraving make new paper dollars at the request of the Treasury??? aside from replacing old paper dollars with new ones are new-additional paper dollars printed in response to the claims for paper dollars that vary from bank to bank??? to meet some type of paper-dollar reserve issues??? what prompts the treasury to create new-additional paper dollars???? on page 43 of harry browne book how you can profit from the coming devaluation a paragraph claims "In modern practice, then, the govt does not print paper money to casue inflation. It prints paper money in response to the inflation that takes place through the bank's deposit-loan expansion." is this true????? are new-additional paper dollars (and coins???) created to meet a banks claim to paper according to some reserve issue??? if that happens are the new-additional paper dollars subject to being inflated upon via existing paper-dollar reserve issues creating a need for more new-additional paper dollars at a later time???? clarification appreciated.
