Well, I do have a pretty good printer. Print, scan, copy and fax. A large ink for black seems to last nearly forever.
Personally, I would just as soon print the targets, but as Joe says, the preprinted targets are cheap enough.
Another thing to take into consideration is that you are just printing a few targets at a time, not a whole slew of them. I think in the grand scheme of things, the cost of printing targets is as nothing.
So, my vote is either way you want to run it. Of course, not shooting much, my vote really isn't worth much.
