I appreciate the steps you've performed to get your customized invoice to be aligned, @SusannaR. 

Let's perform some troubleshooting steps that can help us fix this. To start, use the coarse adjustments if you are using invoices, or forms purchased from Intuit. 

Before doing so, make your continuous-feed printer is turned on, connected to your computer, and that the forms you want to print are in the printer's paper feed. 

Here's how:

1. Go to the File menu, then pick Printer Setup.
2. Select Check in the Form Name drop-down.
3. On the Printer type drop-down, choose Continuous (Perforated Edge).
4. Click the Align, then the Coarse button. Hit OK on the pop-up message.
5. Check the pointer line and note the number closest to the arrow points.
6. Enter this number in the Pointer Line Position field, then OK. 

There is a link to an article that explains how to use QuickBooks' coarse adjustments and fine alignment adjustments: Align checks, invoices, and other forms for continuous-feed (dot matrix) printers. 

I've added this article, Print paychecks for the detailed steps. It provides several ways on how you can print checks in QuickBooks Desktop. 

Let me know how this goes and leave a reply below. I'll be around if you need help printing 1099 forms in QBDT. Have a good one.
