When printing my invoices there is an item column which I don’t need. How do I get rid of this?
Item column is visible only if it contains any information.
i have the same problem item column just appears while the option box in the creation page is blank! i would like to know if and how i can change that column as a numbering collumn?
No, @john_agrigiannis, you cannot change that column to something else without totally recoding the sales invoice template yourself. But you should update your software. The Item field is meant as a shortcut for creating invoice lines and no longer appears on the printed version.
In addition to what @Tut told you, also confirm that you are not using a custom template for your sales invoice. If you want columns to disappear when they contain no data, you need to use the in-built invoice because a custom template (even the “default” one that appears when you create a new custom view template) does not have any of the same intelligence that is programmed into the in-built invoice.
I have created a new custom view template because the address did not line up with the window on the envelope. How can I rectify one issue or the other?
Use the in-built invoice and get different envelopes, or create a new custom invoice template that doesn’t have the column that you don’t want.
ha ha that is the issue how do I delete that column
u can’t lol 
omg
If you are using custom HTML template, you need to edit your HTML template so that column is no longer defined in that template.
