Colour printers and mfp devices are much more common in offices. I find that we are placing as many colour capable devices as mono only especially in offices with only one print device. The reasons are fairly obvious since we live in a colour world and most companies need to be able to produce at least some of their output with colour features.
One of the big fears for new users and even those who have had colour for some time is that 
colour costs of operation will get out of hand. Knowing that users have a tendency to use colour once it is available colour costs are anticipated. The fear however comes with finding that users print everything in colour either without realizing it or just because the default is not setup to avoid this forcing mono printing.
Set a default mono driver
An example of how this can happen is a user prints a colour document from Word and then prints an email from their Outlook. The email includes a link to the sender's web site which will be shown in blue on the email. read more here from the experts at Leppert!!
