Heck, yours is way newer than mine is, lol.. I've had this ol' Lexmark for about 9 years, lol..
Like I said, print out a test on paper, making sure you saved your artwork as a 24-bit Bitmap, then check it.. If it's ok with you on paper, it'll be a tiny bit better (sharper) on the decal paper since the ink won't leech into the paper like it does on copier-paper.. Handle with care until the ink dries too..
Now, here's a BUT, and it's a BIG one..
When you think it's printed out fine, go ahead and start the decal paper BUT:
You MUST use a decal bonder on the decal after you print it... If you don't, the ink will disolve in the water... I use Testor's Decal Bonder... Comes in a 3 oz. rattle-can for about 5 bucks... Don't try to skimp by on clear laquer or something else like it.. Get the decal bonder..
It's also great for saving those old decals you have that may crack or splinter... I've used it on 25-year old decals without a problem...
