OK - if you're fast enough, you can cover a printed sentiment with embossing powder (fine detail stuff seems to work best). Here's an example from way back in my gallery:
To love & to cherish
Get everything ready before you start - take the lid off your EP container, put a piece of scrap paper onto the bit of your printer where your print-out will emerge and preferably swipe over the card you're going to print on with an Embossing Buddy (or used dryer sheet etc - whatever you'd usually use to reduce static when you heat emboss).
Now print your sentiment and as soon as it emerges from the printer, sprinkle your EP on there. Tap the excess powder off onto the scrap paper, tip it back into the container and now just heat your piece as normal.
It's best to go with black for printing - you'll get maximum ink on the paper which will give maximum sticking power. As long as you're using an opaque embossing powder the printing colour won't show. So if you wanted a white sentiment on a coloured base, you'd just print in black and use a white EP over it.
Hope that all makes sense!
