I have a Seikosha printer, but I don't have GEOS.  (If you find a driver that
will support the Seikosha, I will probably buy GEOS.)

In graphics mode the Seikosha thinks it's a Commodore.  That's why the poor
resolution.  I have figured out how to print with more resolution.  But, I
haven't implemented it.  (It's not pretty!)

1. In bit mapped mode, print 3 blank columns.  Print odd row, odd col.  Go
   to the start of the same line.
2. In compressed text mode, print 1 blank (3.5 columns bit mapped).  Print
   even col, odd row.  Set line feed length to 1/2 row.
3. Print a carrage return in text mode.
4. Repeat 1 & 2 and print the even row.
5. Set the line feed length to graphics length - 1/2 line.  Print a carrage 
   return in text mode.
6. Repeat until you finish the page.
