mceit, I had to chuckle at your post. Most large enterprises have purchasing departments to handle procurement. Our org has a purchaser, but our IT department handles any sort of IT purchasing including toners. You aren't using this post on an old thread to sneak in a promo for the services that you offer, are you?
We standardize as much as possible. All of our offices have the same fax machines that take the same toner and drums. We have multiples of each printer to minimize the different toners needed. Each user has Office 2003 installed, and the ones that have been resistant to Office have Word Perfect as well.
