QuickBooks Online Payroll allows you to print paychecks within the Printing section. Since you want to print a paycheck, please check if there are any changes in your Printing Preferences. This way, you'll be able to know if there are any changes or new options in your default printing preferences.
Follow these steps:
Go to the Gear icon.
Under Your Company column, choose Payroll Settings.
Look for the Printing section and click the Pencil icon.
You'll be able to see an option for your printing preferences.
If there are no changes, I recommend contacting our support so that they can further assist you in printing your paychecks.
Here's how:
In your QBO account, select Help (?).
Choose the Search tab.
At the bottom of your screen, click Contact Us.
Type your concern. Then click Continue.
You may choose Callback, Appointment, or Chat as your way to connect with us.
Kindly fill out the provided field such as your First name, Last name, Email address, and Phone number.
Depending on what you choose as your way to connect with us, click Callback, Schedule an appointment, or Chat.
