Subject: Ghostscript (GS22.EXE) problem with Epson LQ-1050?

I just downloaded the GS22.EXE Ghostscript port from
the SIMTEL archive.  Using a VGA monitor, everything
works well (considering I haven't gotten the font
files yet).  However, when I try to print to my Epson
LQ-1050 (-sDEVICE=epson), the resulting image is distorted.

On some lines, the print head doesn't travel as far, leaving
a ragged right border and shifting part of the picture with 
it.  It looks like information is being lost within areas of
totally white space (i.e. no pins firing), and at least somewhat
proportionately to the amount of whitespace in the line.  This 
distinction is especially visible when printing the golfer.ps file.

Is there a "fencepost" error in the Epson driver while printing 
whitespace, or is my case unique?

The printer prints bidirectionally by default;  I did try to
"prime" it first with a command to put it in Unidirectional
mode, but apparently the internal Epson driver in GS22 undoes 
this setting.  I can't see any difference between adjacent 
lines based on the direction of travel, though.

I have also tried removing all TSR's, with no effect.  

In case it matters:
The system is a 25-MHz 386 (Easy Data), with the printer parallel 
port (LPT1:) on an Everex multi-I/O card.

Many thanks for any enlightenment...
