Are written bank checks, to pay your bills, becoming a thing of the past?

Today, is my bill-paying day. i gathered the bills due and my checkbook. then, it hit me….“i don’t need my checkbook”! i have converted all my bill-paying checks to debit card payments. no checks to write, no stamps to buy, no licking a yukky envelope, anymore! Question: paying bills on-line…..is this taking the place of the old-fashioned check and stamp procedure? are blank checks printed anymore for bank customers?
