I thought printer limitations would restrict the printing all the way
around, about the same distance. So you're saying that it restricts
the bottom, but not the top? Vary strange.
Not really - this is to do with the way the printer holds the paper.
If you picture the rollers on the printer, with the print head moving in
front of it.
At the top of the paper, the rollers have a good hold on the paper, and so
the printer can print close to the edge.
At the edges, the same applies - the only limitation is how far the print
head can move (and also that the printer wants to avoid getting ink on the
rollers and other internal surfaces).
At the bottom, the rollers have to hold on to something. The print head
prints in front of the rollers. As soon as the paper leaves the rollers, it
falls onto the output tray. So you cannot print on an area the distance
between the rollers and the print head target from the bottom edge of the
paper.
