Print Speeds
Your printer supports the following burst print speeds in characters per
second (cps).
Printhead Description
Your printer uses dot-matrix impact technology to generate characters. The 248x
has a 9-wire printhead. The 249x has a 24-wire printhead.
248x
The 248x printhead has nine wires arranged in a single vertical column. The
diameter of each wire is 0.30 mm (0.012 in.). The center-to-center distance
between wires is 0.353 mm (1/72 in.). The printhead has an impact force
sufficient to generate readable copies on multipart forms and envelopes up to
and including 6-ply forms (original plus 5 copies).
249x
The 249x printhead has twenty-four wires arranged in two parallel vertical
columns of twelve wires each. The diameter of each wire is 0.22 mm (0.009 in.).
The wires in each of the rows are vertically separated to produce a 0.141 mm (1/
180 in.) space between the centers of adjacent dots. The printhead has an impact
force sufficient to generate readable copies on multipart forms and envelopes
up to and including 4-ply forms (original plus 3 copies).
