Seen on Inhabitat's blog (excellent internet daily reading, bookmark it!), PrintStik is portable small thermal printer [> wiki that], loaded with Lithium-ion polymer rechargeable batteries: pretty cool! Inhabitat's reviewer writes "PlanOn’s printer does run slower than traditional printers and the
quality doesn’t compare to that of laser printers, so the Printstik not
be appropriate for all environments.", - said that, it's for sure an important step for portable technology!
