Well I don't know for a fact that it is, but the customer is a major International Fortune 500 Company and this is an Installation sheet printed and included in one of their product packages, so I would imagine it is an offset press.
Besides, if the commercial printer was using a commercial Laser printer, can't they print 2-sided? There is no problem when it is printed 2-sided, the images align because both margins are offset in the same direction. It is only when it is printed 1-sided (one side to each printing plate) that the problem becomes obvious because the offsets are in the opposite directions. (BTW, it is B&W)
