I have seen posts for color management between computer and printer, but I'm having a hard time finding the answer to color management between a mac and the printer and a pc and the printer. I work in a small office - in my role, I use a mac while the rest of the company uses a pc. The problem occurs when pc users print certain color documents (e.g. our letterhead) on our color printer (HP CP 4025 - yes, it's old!), the colors are off. Our logo is a shade of purple, but it will print out blue. How do I determine the correct colors to use to create the letterhead so it prints correctly from the pc? When I print from my mac, it's correct. The error occurs when the pc users print a word document or pdf.
