Windows 11 Unified Print Dialog Shows "This App Doesn't Support Print Preview" for Multiple Applications

Description:

Hello Microsoft Support Team,

I am experiencing a problem with the new Windows 11 Unified Print Dialogue. I would like to report this issue and request a possible solution.

Problem Description:

When I try to print images or documents from applications that use the Windows system print dialogue, the preview area displays the following message:

"This app doesn't support print preview"

As a result, I cannot preview the document or image before printing.

What I Have Observed:

  1. Applications that provide their own dedicated print preview work correctly.
  2. Applications that rely on the Windows print dialogue display the "This app doesn't support print preview" message.
  3. The issue persists even when I change the selected printer.
  4. I also tried the legacy print dialogue, but it does not provide the print preview functionality I need.
  5. My printer is an Epson L3110 Series, but the same problem appears to be related to the Windows print dialog rather than the printer itself.

Expected Behaviour:

I would like Windows 11 to provide a proper print preview for images and documents before printing, regardless of which compatible application is used.

My Questions:

  1. Is this a known limitation or a bug in the Windows 11 Unified Print Dialogue?
  2. Is there any supported setting to enable print preview for applications that use the Windows print dialogue?
  3. Is Microsoft planning to improve this functionality in a future Windows 11 update?

I would appreciate any suggestions or an official response from the Microsoft team.

Thank you.

My windows 11 version : 26H2 (OS Build 26300.9711)

    Hello @Soumen Biswas

    Welcome to Microsoft Q&A!

    Thank you for your patience, and taking the time to elaborate on your concerns.

    On Windows 11 26H2 (OS Build 26300.9711), this message may appear when an application uses the unified Windows print dialog but does not provide print-preview functionality. Since the issue persists across different printers, it may be related to application compatibility or the Windows print-dialog implementation rather than the Epson L3110 printer itself.

    Recommended troubleshooting:

    1. Install the latest available Windows updates and test printing from another application.

    If appropriate, test the following registry workaround to prefer the legacy print dialog. Open Command Prompt under your user account and run:

    reg add "HKCU\Software\Microsoft\Print\UnifiedPrintDialog" /v "PreferLegacyPrintDialog" /t REG_DWORD /d 1 /f

    Close and reopen the affected application, then test printing again.

    To undo the change, run:

    reg delete "HKCU\Software\Microsoft\Print\UnifiedPrintDialog" /v "PreferLegacyPrintDialog" /f

    Note: This registry workaround is reported in community discussions and is not guaranteed to work on every Windows build or application. There is no universal setting that forces print preview in every application.

    Relevant documentation and discussions:

    Microsoft Q&A: Windows 11 can't do print preview since update

    Microsoft Tech Community: Windows 11 Print Dialog Does Not Support Preview

    These discussions describe similar symptoms and possible workarounds, but they do not confirm a specific bug in build 26300.9711 or a scheduled Microsoft fix. As a temporary alternative, use an application with built-in print preview or export the document to PDF and preview it before printing.

    I hope this helps to better understand the diagnostic options available and the risks involved.

    The unified print dialog cannot generate a preview when the calling application does not supply compatible preview content, and Windows 11 provides no documented global setting that forces preview for such applications.

    What the message means

    “This app doesn’t support print preview” generally means the unified dialog did not receive preview pages through that application’s applicable printing integration. The precise mechanism depends on the application framework and printing API:

    • In the documented Windows App SDK/WinUI printing model, the application prepares and paginates printable pages, then supplies each requested preview page through Paginate and GetPreviewPage. The system dialog displays those app-provided pages; it does not independently reconstruct the application’s document. ^1^
    • Traditional Win32 common print dialogs primarily collect the printer, page range, copies, and related job properties, then return a printer device context to the application. Their documented contract does not provide an automatic document-preview service. ^2^

    This also explains why applications with their own print-preview implementation work while multiple applications using the system dialog do not. Changing the Epson printer would not add preview content that the application did not provide.

    This does not prove that every affected application is defective. An application may need an updated printing integration for compatibility with the unified dialog, or its chosen printing API may not provide preview through that dialog. Ask each application vendor whether the specific application version supports Windows 11 unified-dialog preview.

    Supported options

    1. Use the application’s own preview, where available.
    2. Export or print to PDF, then inspect the generated PDF before printing it to the Epson. This gives you a stable representation of the output. The PDF viewer’s final physical-print step might still use the system dialog, but the PDF itself can be reviewed first.
    3. Check for application updates. Preview generation is application-dependent, so an application update is more relevant than changing printers or reinstalling the Epson driver when printing itself works.
    4. Do not repeat the legacy-dialog workaround. You already tested it, and it does not provide the preview functionality you require. The legacy dialog is designed around print-job selection and configuration rather than equivalent automatic preview generation. ^2^

    Printer-driver repair, spooler resets, and printer troubleshooting are not indicated solely by this message when jobs print successfully and the same behavior occurs with different printers.

    Known-issue and roadmap status

    The current Windows 11 26H2 release-health page does not list this print-preview behavior as an open or resolved known issue. ^3^

    The published notes for build 26300.9539 mention File Explorer preview improvements and reliability changes for Settings > Bluetooth & devices > Printers & scanners, but no unified print-dialog preview fix. Your build 26300.9711 is later, and the available material does not document a fix or roadmap commitment for this message. ^4^

    Therefore:

    • It is not currently documented as a general Windows 11 26H2 regression.
    • There is no documented setting that enables preview for every application.
    • There is no publicly documented ETA or roadmap commitment for changing this behavior.

    Report and track it

    Submit one reproducible report through Feedback Hub:

    1. Press Windows key + F while the message is visible.
    2. Select Report a problem.
    3. Choose Devices and Drivers > Print.
    4. Include build 26300.9711, affected application names and versions, and note that changing printers produces the same result.
    5. Use Recreate my problem to record opening the print dialog and displaying the message.
    6. Search for an existing matching report first; if found, upvote it and add your reproduction instead of creating a duplicate.

    Feedback Hub is the supported channel for reporting Windows behavior and tracking or upvoting existing reports; the Get Help app is intended for immediate support. ^5^
