I don't believe that the IBM printer you have is completely Epson
compatible...you'll have much better luck if you select the CBM-MPS1000
printer driver.  That K is part of the initialization sequence that
your printer is ignoring.  Also, your printer may not support NLQ...
does it do it normally ?

The text processing portion of the printer specific driver was
done as tables + some interpretive code.
(the graphics portion was done as code;  the printers were dissimilar
enough to make that the most reasonable alternative).

I don't know...it is more difficult than to just print a file...
maybe that's why.  A print spooler shouldn't be that difficult for
some enterprising person to write :-)
