Modified the handling of the "Sort Invoices by customer Category" (Modification #813) in Print Invoice so that when this option is enabled, the category subtotals will be printed at the end of the invoice rather than appearing separately at the end of each category section.
Updated version 3.6.9 5/3/12:
The Category detail will break out the Category Sub-total, Category Sales Tax and Category Total amounts when printing the Category Summary at the end of the invoice.
Updates Version 3.6.10 - 7/9/12:
a. Invoice sub-total value will be printed before the Sales Tax amount is printed.
b. Category headings and sub-totals are not printed.
c. Updated the way that the customer category breakdown is printed so that the sub-totals are printed at the end of the invoice.
d. A title line will be printed with column heading (Category, Price, Tax, Total).
e. The category summary will no longer be printed on Loading Sheets. Now the summary will only be printed on Invoices and Credit Memos.
