"Cheap" probably has little to do with it. My Officejet was designed for
small-office duty. It's largish, rugged, and hardly cheap in its day.
The "cheap" version at the time was the PSC 2110 that I mentioned. Yet
neither of them had the same shutoff feature as the 5650. Instead, they
had a sort of sleep mode, which was as you describe. Personal
speculation is that the lack of it had something to do with the scanner
bulb, but I have nothing to really base that on.
However, I can tell you that for a while I ran the PSC without turning
the printer's switch off, but by switching everything off with a power
strip. Bad idea. Every time I powered up, the printer and scanner would
initialize. It is my belief that the practice led to the early failure
of the scanner bulb, due to the many start-up cycles, and that meant the
printer was gone, too. I now keep the Officejet switched off with the
printer switch unless I am going to use it, and I use it for "special"
jobs. For everyday, knocking around, throwaway stuff, I use the 5650.
In my case, the 5650 was the "cheap" printer. I picked it up at a
rummage sale for $1. It needed a power supply brick, which I found on
Ebay for $15. The Officejet was about $70 used, also on Ebay. Both
happened to based on the same print engine and cartridges as my
then-failing PSC, one of the reasons I selected them.
