In 1986, mimeograph machines were (for the most part) replaced by digital copiers in elementary schools. Those of us teachers who experienced using mimeograph machines will forever remember the distinct smell of the still_damp, purple_ink worksheets that we handed out to our students _ by the ream full. (If you're like me, you can remember that smell right now!)
Math worksheets don't provide immediate feedback _ Most teachers are familiar with the long delay between when students complete a worksheet, and when they get their correct page. Most don't get anything back until the next day or the next week. In the meantime, the students continue to practice incorrectly. It's no surprise that immediate feedback has been shown to increase student performance and diligence. Unfortunately, math worksheets have no mechanism for keeping a student from moving to the next problem until after they demonstrate understanding.
