RE: Print a Transfer order
You can’t natively print a Transfer order.
The absolute bare-bones (no scripting) method would be to create a saved search for transfer orders, then create an Advanced PDF template based on that search (read: Advanced Templates for Printing Saved Search Results). You would then create a hyperlink field that points to your saved search (read ‘step 5’ of this)
However, the above only creates a link on the Transfer Order. To get an actual print button, you have to do some amount of scripting.
To get you on the right track, read the answer to this question and also SuiteScript 2.x Module and Members for Printing Transaction Records
