Hello, bowtie_david. 

Welcome to QuickBooks Community. I'll share some steps to ensure you're able to print checks. 

Here's how to rename the QBprint.qbp file:

1. Locate the QBPrint.qbp file.
   Quick tip: You might need to display hidden files and folders or search for files using Windows to find these files in Windows.
   • Windows 10, 8.1, 8, 7 and Vista: C:\ProgramData\Intuit\QuickBooks 20XX
     Note: 20XX represents the version of your QuickBooks
   • Server 2008 and Server 2012: C:\Program Data\Intuit\QuickBooks year and C:\Users\**remote user**\AppData\Roaming\Intuit\ YEAR VERSION\TSPrinterSettings
     Note: Terminal Service users report finding duplicate copies of the Qbprint.qbp file with the stored client data files; double-check all folders for odd instances.
2. Right-click the QBprint.qbp file for your QuickBooks version and select Rename.
3. Add the word old to the file name (i.e. QBPrint.qbp.old)
4. Open QuickBooks Desktop.
5. From the File menu, select Printer Setup.
6. Select any transaction in the Form Name list and select OK. This will create a new QBprint.qbp file.
   Note: You do not have to do this for every transaction.
7. Try to open and print any transaction.
