What is a Character Cell?
A character cell is the rectangular array of locations at wh ich dots can be printed to form one
character.
All character cells for a given monospaced font at a gi ven pitch are the same size. If you print a
line of characters with no countermanding motion instruc tions, then no character cell will impinge
horizontally on the character cell of an adjacent character . You can determine character cell width
in a monospaced font by measuring the distance from the leading edge of, say, an uppercase “E”
to the leading edge of an adjacent uppercase “E”.
In an impact-matrix printer font, the printed portion of a c haracter is often centered horizontally in
the character cell. There might be a fixed number of dot colum ns on either end of the character
cell that are never printed. This is analogous to the side bearings in a typeset character.

In the oversized font, on the other hand, characters are lef t-justified in the cells. This lets you print
a larger character when you are printing, say, one huge character on a sheet. The 7265 printer
prints as much of an oversized character as will fit betwe en the margins. If your character is going
to be clipped at the right margin, then you might rather clip th e side bearing than clip a printed
portion of that character.
In the oversized font, the topmost dot in the uppercase “E”, f or instance, is centered on the upper
boundary of the character cell. The lowest dot on the descend er of the lowercase “j” is centered
on the lower boundary of the character cell.
