Which of these requires a separate drum: M118dw, M102w, & M29w?

I am thinking about replacing my P1102w that I've had for 6 plus years, with one of these three entry level monochrome printers: M118dw, M102w, & M29w. In case anyone is wondering why, the P1102w is working fine now, after having printed up just over 71,000 pages. I could probably squeeze another 2-3 years out of it, but if I can sell it now for half of what I'd pay for a new one, I think I might want to make that move.

Now I was reading on a review, that the M118dw requires a separate drum. On the HP.com page for it, a drum is listed in the "Toner & Paper" section of that printer's page. I didn't see any drum listed for the other two printers. One of the things I've enjoyed about hp lasers is that they haven't required a separate drum.

Of these three, does only the M118dw require a separate drum?

And if so, does the "d" in the product name (M118dw) indicate a separate drum--as in, if it doesn't have a D there, it doesn't need a separate drum?

The "D" in the name indicates that it has a built in automatic duplex function, it has nothing to do with the drum unit. The "W" indicates unit has wireless networking. According to specs the 102 uses a separate drum and toner. The M29W uses a one piece toner/drum unit like your current printer.

Thanks.

Would the M118dw also use a one piece toner/drum?

No the 118 uses a separate drum and toner setup
