I've printed pano's up to 36" on my 3800, it can be a bit tricky to get the paper to feed right but it works.
Now I have a pano that's 40" long, I've heard of people doing this on a 3800 using a inexpensive third party app, but for the life of me I can't find it.
I don't want to spend a lot money on a fancy rip, I could just send it out, but I thought I'd run my question by here first.
Thanks for any help.
