In order to keep options in workflows lean then Katana lets you change which templates are available in print menus.

In order to hide / show a template in a print menu:

1. Open "Settings" -> "Print templates"

2. Tick or untick "Visible" column to unhide or hide templates

3. This is then shown in the print menu of the respective document in Katana (for example: manufacturing order)

Read here about how to reorder your print templates.
