A paycheck in the register will appear as split if there are multiple affected accounts such as Payroll Wages, Payroll Taxes and bank accounts.
Here's how to confirm and verify the posting accounts of your paycheck:
Hit the Lists menu and choose Chart of Accounts.
Double-click the account to open the check register.
Open the paycheck by clicking it twice.
Click Reports tab at the top.
Select Transaction Journal.
To learn more about paychecks, I recommend checking this link: Payroll 101.
If you're referring to the Check Styles, you can select and print the check as Voucher, Standard or Wallet. Choose your desired formatting according to your preferences. For more details, refer to this Create, modify, and print checks article and proceed to the Print Checks section.
That should help you correctly print the paycheck, @thmboro. Keep me posted on the results or if you meant something else. I'm still here to help you more.
