Black and white inversion on Samsung ML-2010

I have an old Samsung ML-2010 that has obtained a strange problem. When printing a PDF, image, or from chromium what is suppose to be black and white is inverted. In order to print an image, I had to use GIMP to invert the colors. Printing the image with inverted colors caused the image to be printed properly.

When doing a CUPS test print the colors are not inverted. Does anyone have an idea on how to fix this problem?

Printer: Samsung ML-2010
Driver: SpliX V 2.0.0

What operating system are you using?

It was being used with Arch GNU/Linux. The printer has been replaced after I posted this thread. Though, if you have any ideas of the cause, I am still curious.
