It seems that the average Canon printer engine is only nominally 300 dots
per inch. All the ones I have seen with Imagen labels have been more
like 297 x 302. The ones with Apple labels have been something else, I
forget what. But only within +/- 1% or so. One would like to believe
that this is adjustable, somewhere in the hardware.
