I think that assumption is wrong. For me I have had my printer since 2011 and have printed less than 4,000 pages. I often go months between print jobs. Sometimes I print, sometimes I scan, and sometimes I photocopy.
Basically a ream of paper a year sounds like not a lot by office printer standards but not a trivial amount either. With travel, I probably can go months without printing, but I'd still say I print "regularly."
