Thanks for joining in this conversation, @JJP5. The steps shared by my peer are for QuickBooks Online. Let me help correct the alignment when printing checks in QuickBooks Desktop.

QuickBooks lets you use coarse and fine adjustments ib setting up your printers. This will help align checks, and other forms purchased from Intuit.

First off, let's ensure you use the continuous-feed printer and should be connected to your computer. Please know that other continuous-feed forms can't be adjusted using this method. Hence you won't have to make fine adjustments if the coarse is successful.

Here's how:

1. Go to the File menu, then select Printer Setup.
2. Select the type of form in the Form Name drop-down list.
3. Choose Continuous (Perforated Edge) from the Printer type drop-down menu.
4. Click the Align button.
5. For business forms, select a template to use for alignment, then click OK, then select the Coarse button, then click OK on the Do Not Adjust Your Printer pop-up message to print a sample form.
6. Check the pointer line that QuickBooks printed across the middle of the sample, and note the number closest to the arrow points. Enter this number in the Pointer Line Position field and click OK.
7. If QuickBooks prints a third sample when you click OK, something is wrong with the sample test print. Check your printer settings and make sure you are not adjusting the printer manually.

Now, let's make fine adjustments, here's how: 

1. Go back to the File menu, then select Printer Setup.
2. Select the type of form in the Form Name drop-down list.
3. Choose Continuous (Perforated Edge) from the Printer type drop-down menu.
4. Click the Align button, then select the Fine button, then click OK to print a sample form.
5. Check the alignment grid that QuickBooks printed on the sample to estimate how far to move the text.
6. In the Vertical and Horizontal fields, enter a number to specify how much and in what direction to move the printed text on the form.
7. Click Print Sample to test the alignment, then select OK when the fine adjustment settings are correct, then click OK to close the window.
