Color and grayscale are probably reversed

[Victor Porton]

Debian Linux "testing"

$ pcal 03 2014 > ~/t/cal.ps

(Note that the file cal.ps is attached.)

$ cat ~/t/cal.ps | lpr -P Deskjet_1050_J410 -o PageSize=Letter -o PageRegion=Letter -o InputSlot=Auto -o ColorModel=RGB -o MediaType=Plain -o OutputMode=Normal

prints black and white.

$ cat ~/t/cal.ps | lpr -P Deskjet_1050_J410 -o PageSize=Letter -o PageRegion=Letter -o InputSlot=Auto -o ColorModel=KGray -o MediaType=Plain -o OutputMode=Normal

prints high quality grayscale (or maybe color, my .ps is without colors).

So the modes ColorModel=RGB and ColorModel=KGray are reversed!

Don't forget to test also ColorModel=CMYGray
