I have a 1204 and YES, you can print on laminate. I did it on a rush job for a customer a few years back, let him know what I was doing and to please let me know if they didn't work out for him. I followed up with him about 6 months later out of curiosity and he said they were working fine.
I also printed on laminate once and overlaid it on chrome vinyl, domed it and it gave it a really cool effect.
I'm not really sure because it's been a while but I believe I used Oracal 210, I do remember I had to turn my heat settings down. You might have to play around a bit.
I would let your customer know though, I think honesty is good and if they know you need feed back they're usually happy to be helpful in matters like this
