Any inkjet printer and flatbed combo. Printing uses around 20 watts and scanning uses about the same. So the lowest wattage inverter would work but you would probably want a higher quality inverter than usually found in the under 100 watt group.
You need to talk to the RV groups about battery requirements. Some of the full timers can tell you about their experiences with computer equipment.

I use an HP1012 B&W and HP2600n Color laser printers in my RV running off a 2000 watt modified sinewave inverter with batteries and solar panels. I use laser printers so that the cartridges don't dry out on me and the printers are always ready to use.

These printers use a miniscule amount of current except when actually printing and the fuser turns on. This draws about 300 watts during the time when the page of paper is actually moving then it turns off. Sleep mode is at near zero power.

A laserjet uses 10 to 20 times as much power as an inkjet. You don't want to run a laserjet in a trailer not connected to AC unless you have at least 2 heavy golf cart batteries and you need an $1800 solar panel to maintain the batteries.

Well, I have 4 golf cart batteries and 600 watts of solar panels. But, it only takes about 2 watt hours/page to print with a laser printer. If you printed pages continuously for a full hour it would take about 25 amp hours from my 440 amp hour battery pack. I rarely print 600 pages in one shot.
I agree with George, you need a printer that doesn't require heating to print. That rules out laser (color or black and white), probably dye transfer, and also solid ink.
That pretty much leaves inkjet. Even the thermal head printers draw low current.
The one issue to consider with an inverter is if it will work on a hard cut off or not. I suspect running a printer below it's current/voltage needs can be bad for it's power supply and logic circuits.
Of course, that could lead to some "printus interuptus" so make sure the batteries are topped up ;-)

One of my laser printers dims my house lights... yes, in a hard wired standard AC HOUSE with a fairly balanced C.B. box. That's how much energy some can use (it is an older model, admittedly).
