I work at a tire and alignment shop here in California. You HAVE to give the customer a printout of the alignment to prove the vehicle required adjustments. If we can't produce a printout we cannot charge for the alignment.
A readout with close to 0 degrees Camber and a 0.75 to 1.00 degree Caster split leading to the left, and toed in about 0.10 on both sides is usually pretty good. A good alignment tech can also make necessary adjustments by looking at the tire wear if the tires have been on the front for a while and no parts have just been replaced.
