You'll need a pretty big pocket to hold the Pocket Printer A6, which hit computer and office store shelves last month. A better place might be a briefcase, purse or laptop carrying case. The pocket printer is small and lightweight and not a burden to carry around.'' Though it comes with an AC power adapter, the printer also runs on four AA batteries. Rolled paper, similar to the type used in early fax machines, feeds from inside the machine.
Single sheets are also available.
The printout, at 400 dpi, looks like just another document when enlarged. We don't miss it until we need it.
