Hi Kermit
that is exactly the step that gave me all the greif when making my own.
even though I used a laser printer, I followed the written instructions and went on to try to seal them. (the paper curled, the ink ran, and the decal would not release once it had dried) I tried with future and also with tamiya clear (from a can). after several attempts I decided to try to apply them unsealed... and that worked a treat. however they were laserprints which are waterproof.
If you have to much trouble you may be able to get waterproof inks for your printer as a last resort.
best of luck
