I bought the HP M281fdw, which might be hard to find now since its model year was already being phased out when I bought it. I found the list of models that white toner cartridges are made for on the ghost-white-toner site. Those cartridges are definitely pricey, which is why I'll probably just stick with white laser decal paper for jobs where I need white. Still wanted the capability though, so that influenced my printer decision.
It hasn't been discussed much, but just in case you're looking for an opinion on what paper to get, I'm using a brand called Sunnycopa which is specifically made for laser printers. Compared to the MicroMark paper I have, it is definitely better. I'm pretty sure they also make paper for inkjet printers if you ever want to look into that brand as well. Got mine from Amazon, and my Sunnycopa laser paper required no fixative. Tried the same test with the Micromark (I think it was inkjet paper, so that may be why), and the toner cracked and started flaking off the paper, even with careful handling. I was reading the MicroMark instruction sheet, and it does say that either printer type will work with the inkjet paper, but that both require a fixative. With the Sunnycopa paper, I applied it carefully to a small sheet of styrene, and then deliberately tried to rub the color off of it. All of the color stayed put then, and stayed put with MicroSet and MicroSol applied to it after getting it in place. No Krylon goo either.
