My checks are printing too high on my new printer. How to you align them? I'm a Quickbooks idiot.

You'll have to use compatible checks when printing, deb3756.

Then, correctly align your new printer to print checks. 

Here's how:

1. From the File menu, choose Printer Setup.
2. At the Form Name drop-down choose Check/Paycheck.
3. For the check style, select Voucher check.
4. Click Align on the right.
5. Print a sample and compare it to your pre-printed checks.
6. Using the grid on the sample adjust the horizontal and vertical settings; then click OK
7. Click Align again and Print another sample.
8. Compare the sample to your paycheck stock and adjust the alignment again as necessary.
9. Repeat steps 4 through 8 until you have the alignment perfect.

Please check this article for the complete steps: Align Checks, Invoices, And Other Forms.

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