R12 check printing output text file

Hi,

We are upgrading to EBS R12. Currently in R11, we defined check format and used in bank account payment document setup and AP check runs create .txt files with check data and we send the .txt file to a third party software LinkUp to print checks. LinkUp store all formatting, logos, signatures, etc and handles all information not in the .txt file.

I know R12 can do check printing with xml publisher, but our business wants to keep the Oracle-Linkup integration for now. My question is, how can we set up R12 payment module IBY to output .txt files? I just want to output check data in text files in exact layout as we are getting from R11, so we do not need to touch the third party application.
