printing checks with all in one printer

I have an HP Officejet 6310 All-In-One printer and need to print checks. When I went to print the checks it printed the checks from Z to A. How do I get the checks to print from A-Z? I need them to print from A to Z as the software assigns the check numbers to the checks based on what I put the starting check number is and the software puts the checks in alphabetical order.

I appreciate any assistance you can give me.
