Printers are classified by how much output they produce per print cycle: a character printer prints one character at a time, a line printer prints one full line at a time, and a page printer prints one whole page at a time.

A dot-matrix printer is an impact character printer — its print head carries a matrix of pins that strikes an inked ribbon to form a single character at one horizontal position, then the head shifts to strike the next character. So the blank is filled by "one": it prints one character at a time.

• Line printers (e.g., drum or chain printers) print an entire line in one cycle, not a single character.

• Page printers (e.g., laser printers) print a whole page per cycle.

• Only the character-printer class — which includes dot-matrix printers — works one character at a time, confirming the fill-in as "one".
