Printing
Problem
Solution
The printed position
is not what you
expected (continued).
Vertical printed
lines do not align.
The loading position of the paper may be
too high or too low. Use the micro-
adjustment feature^ to reset the loading
position so that the perforation is centered
within the skip area. Refer to 3-12.
Your application program may be setting
the top and bottom margins. If this is the
case, turn off skip over perforation by
setting DIP switch 2-3 to OFF. Refer to
3-10.
The printer may be set for bidirectional
printing. This can cause a slight
misalignment of graphics characters. When
precise printing of vertical lines is
necessary, select the unidirectional print
mode by sending ESC U or BSC < to the
printer. Refer to 9-9, 9-10. Unidirectional
printing is somewhat slower.
