Hi Microsoft Edge Support Team,

After updating Microsoft Edge to version 149, we are unable to open Print Preview and perform printing. During further investigation, we found that adding the following entry into the URLAllowList resolves the issue:

chrome-untrusted://print

Could you please confirm whether this behavior is expected in Edge version 149? Previously, we tested the same scenario on Edge version 148 and did not encounter this issue.

Please refer to the attached screenshot for more details.

    Hi! With URLBlocklist = *, Edge is configured to block all URL patterns unless they are explicitly allowed. URLAllowlist is intended to create exceptions to restrictive blocklists, and the allow list takes precedence over the block list.

    However, I would not say that this is a specific Edge 149 print preview bug or intentional change, because Microsoft has not released a note that specifically says “Print Preview changed in Edge 149.”

    But it does appear to be an expected side effect of using URLBlocklist = * with Edge internal pages, although the difference between Edge 148 and 149 may be due to an internal implementation change in the print preview page.
