How do I adjust the written amount and Vendor Name on my cheques?

Hi there, lmcwhirter-nictr.

I'm here to ensure you can print the cheques without issues.

Let's configure the print settings. Before doing so, make sure you have QuickBooks-compatible cheques. If you want to purchase one, you can visit this page: https://intuitmarket.intuit.com/

If you're already using the correct cheques, let's fine-tune the alignment. Here's how:

1. From the + New tab, select Print checks.
2. Select Print setup.
3. Select No, continue setup. Then select No, continue setup again. 
4. After adjusting the grid, select View preview and print sample. Then select Print.
5. Follow the on-screen steps to finish printing your sample check
6. Check the alignment of your sample one against a blank check.
7. Repeat the grid alignment process.
8. Click Finish Setup.

If the same thing persists, let's configure the printer dialog box. You can check this link for the detailed steps: Configure your printer dialog box.

Once everything's good, you can print the checks again.

You can always post in the forum if you have other concerns about printing cheques.

So from what I understand, I can only configure "QuickBook Cheques".  If I have other cheques from my previous program, they will not work with your program?

The only option to configure my cheque is the $ amount and Date, no other areas are eligible to be adjusted?

Hi there, @lmcwhirter-nictr. 

I'm here to add some clarifications.

If  you're using your own checks to print, they need to be formatted for QuickBooks. You can order QuickBooks compatible checks from Intuit to ensure the compatibility of the alignment.

Let me show you how to set up print checks in QuickBooks Online:

Before you start, load some blank paper into your printer for your test prints. That way you won’t waste actual checks if you need to fix the check alignment.

1. Select + New.
2. Select Print checks.
3. Select Print setup.
4. Select your check type, voucher, or standard.
5. Select View preview and print sample. Then select Print.
6. Follow the on-screen steps to finish printing your sample check.
7. Put the sample print under a blank check. See if they line up correctly.

Lastly, I've got some resources that you might need for additional information on how to fix print alignment for preprinted checks in QuickBooks Online.
