Help

If Printwhisk is not showing up in your print dialog, or a letter is not moving the way you expect, start here. For anything account-specific, email hello@printwhisk.com.

Install troubleshooting

Use 64-bit Windows 10 or 11.
Run the installer as an administrator when Windows asks.
SmartScreen / unknown publisher: the installer isn't code-signed yet, so Windows will warn about an unknown publisher. If you trust the download, choose More info → Run anyway. If Windows still blocks it, download again from the download page and verify the SHA-256 checksum listed there.
After install, look for Printwhisk in your normal print dialog (File → Print).
Logs: %LOCALAPPDATA%\Printwhisk\install.log (installer) and companion.log (background app). Re-run the installer if the printer is missing.
Restart the companion: Task Scheduler → Printwhisk Companion → Run, or sign out and back in.

Print job not accepted

Printwhisk needs a PDF from Windows. The installer registers an IPP printer that converts jobs to PDF automatically. If you see a browser tab about an unreadable print job, reinstall from /download so the IPP printer is recreated (do not use a manually added TCP port).

Printing a letter

Print from any app and choose Printwhisk.
The first print opens onboarding in your browser.
Create an account, add your mailing address, add wallet funds, then confirm the letter.
Your outbox shows the 10-minute cancellation window before the letter goes to production.

Refunds, cancellation, and delivery issues

You can cancel from your outbox during the 10-minute hold. If the hold has passed, contact support and include the email address on your account plus the letter title or approximate print time. The full rules are in our Refund & Cancellation Policy.
