For me, I'm using a passport color checker in the field - then create a profile in Lightroom and apply to the pictures. On my monitor, I've got an Xrite that works well. I guess the next step is to get my printer profiled, but paying tuition on 2 college students and the printer has a clogged black print head are putting that off.
Take a look at the online seminars that X-rite offers. It's easier than it seems if you get a workflow and stay consistent.
