Sales Order Invoice Printing

For some reason, on one of my workstations, when I create an Invoice in Sales Order Invoice Entry, I cannot print the range of invoices when I try to print them from Sales Order Invoice Printing.  I've noticed that when I create Invoices on this particular workstation from Sales Order Invoice Entry, the checkbox next to "Print Invoice" on the Header tab is NOT checked.  In order to print the range of Invoices I created, I need to go into each invoice individually and check that "Print Invoice" checkbox, then when I go to print the Sales Order Invoice printing, I need to check the box that says "Print Invoices Already Printed"

The odd thing is that I didn't need to do this before.  This started happening a few weeks ago.  Also, if I create an Sales Order Invoice Entry on another workstation, that box is already checked and I can print the range of Invoices without a problem?  

Can someone please advise?  Thank you.
