How can I check my printers (MFC-J625DDW) total print pages by computer or printer?
For anyone who stumbles across this question looking for the same answer, the page count should be listed on the user settings report. Instructions for printing that report are on page 37 of the Advanced User's Guide, but basically it's just:
Menu > Print Reports > User Settings > Start
If the page count isn't listed on the user settings report, then you'll have to get it from the web interface as @hdhondt suggested.
