I woudl recommend AGAINST a laser printer they are voltage senistive (DO not like lower voltages) and may not properly fuze the print if voltage is low. Draw a lot of power too.. ink jet is more to my liking for mobile use.
ANY ink jet save Epson.. Not thrilled with Epson. Have used HP and Canon Both with no issues. B*W only or color is your choioce (I like color)
I also choose Canon because I from time to time "Print" CD's and they can do that. (Get an inkjet printable CD or DVD and they will label it at least the ones I buy will. not all do)
