Formatting individual lines of printing template

Hello,

I am trying to hide some orders in the printing template.

For example

[ORDERS:Void]
<J00>- {QUANTITY} {NAME}|**Void**
{ORDER TAGS}

allows line level formatting of orders that have been void.

I'd like to do the same for groups

[ORDERS:ORDER GROUP:BAR]

and specify an empty line to orders that have group code : BAR are not displayed

Ideally I'm trying to make sure that all orders that belong to GROUp CATEGORY BAR are not displayed.  I have various departments and when the orders are punched into the POS, I want the printer to print various KOTs department wise, so i figured the best way is to create multiple printer templates for each department/group code. and have it execute multiple print jobs.
