Epson LQ-950 Prints Jagged Characters or Vertical Lines (85984)
The information in this article applies to:
- Microsoft Windows 3.1
- Microsoft Windows 3.11
This article was previously published under Q85984 SYMPTOMS
When you print from Microsoft Windows 3.1 to an Epson LQ-950, jagged
vertical lines or characters may result.
CAUSE
This problem may be caused by the bidirectional printing option within the
Epson LQ-950 printer.
RESOLUTION
On the motherboard of the Epson LQ-950 printer, there are two banks of
switches. To correct this problem, on bank 1, turn switch 5 to "On" to
set the printer to unidirectional mode instead of bidirectional mode.
MORE INFORMATION
The jagged lines and character problem usually occurs with specific
characters or vertical lines within the document, not randomly. The
problem is in the way the LQ-950 interfaces with different drivers
used to emulate it, such as the Epson LQ-2500 or LQ-2550. It will
print these graphics in a bidirectional pattern, that is, it is
approaching the area from a different direction every other time. This
creates the appearance of a jagged edge because graphical characters
are printed out of alignment.
