Laser printers lifetime

Just took delivery of a Brother HL-2170W monochrome laser printer.
Curious as to whether or not it should be left on 24/7. A Google search
was inconclusive since many of the postings were either very dated or got
off topic.

Discounting electrical consumption is it better or worse for the printer
to be left on 24/7 as opposed to shutting it down each day after use.

As a footnote the old HP inkjet it replaced was on 24/7 and outlast two
computers.
