I'm very late to this conversation, not having checked into the forum for some months, but I have printed all my own decals on a laser printer, with (to me) acceptable results. I find that the edges of the decals need 'touching in' with paint matching the base coat they are applied to, as the white paper they are printed onto shows at the edges.
Interestingly, I recently ordered more of the 'same' paper from the supplier, (Crafty Computer Paper) and I can no longer produce good quality prints - it appears that the formulation of the paper has changed, and now there is a very narrow range of printers that they recommend for printing on - sadly not including mine
However, I used a friends inkjet and some of their inkjet paper, and have produced decals of the same quality - but you must apply a layer of lacquer to the finished, dried decal before applying it to the model.
I've attached a couple of images showing some of the decals I have produced.
