Printers — they're never terribly exciting. And the market for stand-alone printers, as distinct from multifunction devices (MFD), is one that's been steadily eroding, which isn't surprising when you see MFD devices in your local tech emporium for significantly less than $100. As such, any stand-alone printer (excluding portable photo units) has to work extra hard to stand out. The D4360's big claims in the design department rest around it being small and fairly cheap to both own and operate. To an extent this has appeal; if you genuinely don't need a scanner/copier/fax, then why waste desk space or money on one?
The D4360 measures in at 148x445x342mm, well below the size that most MFDs will take up, and its carrying weight of 3.5kg is moderate. We wouldn't want to lug it around all day, but it's certainly not going to snap your spine if you're moving it from site to site.
The D4360 is, as noted, just a printer. No scanner, no copier, no fax. HP does hype it rather strongly, however, with a very prominent sticker on the top of the printer body proclaiming it as having the capability to print "laser quality text" — and those are fighting words indeed. In speed terms, HP rates it as capable of chucking out up to 30ppm (pages per minute) in black and 23ppm in colour modes, which is swift enough if it's true.
Connectivity on a sub-$100 printer is never going to be exceptional, and the D4360 ships with only USB connectivity; from the rear to connect to either a Windows (2000/XP/Vista) or Mac OS (10.3.9 or better) PC, and from the front to connect to digital cameras and other USB devices. Bear in mind, however, that this isn't the same as having PictBridge compatibility; you'll still have to have a PC connected to actually print anything from your USB device, which begs the question as to why HP bothered to throw it there in the first place.
