A few more details on exactly what is happening (or not) would have been helpful.

For starters, please try this:

How to Repair Printer Setup:

Try resetting your printer definitions in Quicken and then redefine the printer:

For Quicken for Windows versions 2009 and older:

• Close Quicken
• Use Windows File Explorer to locate and rename the file
  C:\Users\_username_\AppData\Roaming\Intuit\Quicken\Config\WPR.DAT to WPR.OLD
• Now set up your printer again, as described below. The WPR.DAT file will be recreated next time you start Quicken.

For Quicken for Windows 2010 until Quicken Subscription (US, 2021) R33:

• Click File / File Operations / Validate and Repair. Click "Reset Quicken Printer Settings", then click OK.
• Now set up your printer (see below)

For Quicken for Windows  Subscription (US, 2021) R34 and newer:

• Click File / Validate and Repair. Click "Reset Quicken Printer Settings", then click OK.
• Now set up your printer (see below)

Printer Setup (all versions):

• Close and restart Quicken (might not be necessary, but it can't hurt)
• In Quicken click File / Printer Setup / For Printing  and visit all selections as needed
  (a) for Reports,
  (b) for Checks,
  (c) for Invoices [Quicken H&B, RPM users only]
  and define your printer.

If you're printing checks, do not forget to select the correct check style.

• For 3-per-page personal size checks choose "Wallet Checks (Check 21 ...)", not "Wallet Checks" (unless you still use some very old stock from many years ago)
• For 3-per-page business size checks choose "Standard Checks", not "Voucher Checks".
• For 1-per-page business size checks with 2 stubs choose "Voucher Checks".
• Canadian users need to choose between 2 layout styles, e.g., old style "Voucher" vs. new style "Voucher - Image ready".

(Optional) If you are printing a logo (image) on your checks, click the Logo button and make sure that your logo image file is still where Quicken expects it to be.
Also choose the proper features for printing partial pages when using 3-per-page stock.
Users of continuous forms on dot matrix printers: Be sure to select "Continuous Forms" instead of "Page-oriented".
Laser / inkjet sheet-fed printers: select paper size 8.5*11", standard paper. Do not use any "Auto detect" or photo print settings.
If checks print OK on one computer but do not align properly on another computer, compare printer settings and printer port selections.

Make sure that at least one of your printers is marked as Windows Default Printer ... doesn't have to be the one you want to use with Quicken, but you need at least one marked Default Printer

In some of the newer versions of Windows 10 you may also need to do this:
Go into Windows Settings or Control Panel, Printers & Scanners.
Uncheck "Let Windows manage my default printer".
