HP Wireless Printer/Scanner/Copier for $49. Bonus: No sales tax.

True.

Videre est credere (above).

The ad up top appeared on page A18 of Friday's Washington Post.

That's cheaper than it would cost to buy just the ink cartridges.

I have one of these HP e-All-In-One Printers.

I bought it about a year ago and it's working nicely.

Plug it in and you're ready to set it up to print — without a wired connection to a device.

So simple even a TechnoDolt©™® can do it (one did!).

It's all well and good to print from my Air or iMac from anywhere here at home, but the wondrousness is when you're using your iPhone or iPad outside your house, say in another city or state.

Take a picture or happen on something online, touch the curved arrow icon on the screen, touch "Print," and up comes a screen that says "Printer Options — Print 1 Copy."

Touch that and your printer tucked away at home churns out a very acceptable color rendition.

Still amazing to me.

Perhaps it even works from another country, I wouldn't know.

Note the following:

• You have to buy your $49 printer in the state of Virginia

• The offer ends today (Sunday, August 5, 2012)

Fair warning.
