corrections in my invoice printing application -- 2

I am looking for an experienced freelancer to help me with correcting an invoice printing application. I need changes to be made to the existing printing feature and I have identified the most important issue that needs to be addressed – the need for an 80mm printing style. The other corrections needed include the addition of a minimize button and fixing the visual layout of the program. An additional feature I'd like included is one for automatic printing. It is also important to resolve any technical issues with the printer. This project is especially pertinent to me and I am looking for a skilled freelancer to help me with this task as soon as possible.
