JavaPOS Printer setup

Equipment: New POS terminals using Win7 Home Premium & Floreant POS 1.03. Will not print at all when printer type is set to "javapos" in Floreant "Back Office". When printer type is set to "normal" 58C ( 58mm printer with cutter ) Windows Test Page prints a small strip of text down the left side of the receipt. When a ticket is printed from within Floreant, it gets cut off on the right hand side. The OEM advises me that it is trying to print to an 80mm roll instead of 58mm. What I can find on the internet is that I need to use iReports or something to decompile the jasper files and recreate them as .jrxml so they can be edited. WILL print printer self test pages perfectly.
