When printing a document on a printer with separate color and bw page counters for billing purposes, it's important to get the printer to not print color unless absolutely necessary.
In this case I'm using a laser printer (XEROX WC 7220), but it's the same with most printers.
The issue reveals itself when printing large page count documents that have a couple of color information but the printer still counts all the pages as color, when the logo is present.
If I use text only then the printer is actually able to single out automatically which pages have color from which do not. The issue I'm interested in solving is when using an image, or more specifically a logo.
The logo I'm using has black and grayscale elements and is saved as PNG. I imported it to Photoshop and changed the color mode to grayscale, to make sure it was BW.
When imported to Word the image is always considered as having color. Is there a method or image format that will unequivocally only have Grayscale values, without losing image detail?
What I'm NOT looking for:
- Info on how to print a page black and white
- Formatting an inserted image as "black and white" or "grayscale" - it doesn't make any difference
