BleepingComputer reported on 13 November that Microsoft has warned its November 2026 Windows security updates may break printing for documents with complex formatting. In a service alert, Microsoft said printing might fail when a document holds an image with a height or width of zero at the chosen print resolution. The issue covers Windows 10 and later, and Windows Server 2016 and later.
Microsoft said these images can be invisible, such as watermarks or layout anchors. Some document tools also insert image objects when no graphic is present. The bug mainly affects Word documents printed through GDI, the Windows Graphics Device Interface, which draws the page for the printer. Other apps may fail too. A zero-size image covers no area on the page. Microsoft has not said why that stops a print job. BleepingComputer's report gives no fix date or count of affected users.
BleepingComputer notes that Microsoft also addressed printing faults after updates in March and July 2025, and in August 2026 said .NET Framework updates broke printing in WPF apps. Update tests that print only plain pages can miss faults tied to document content. Three questions for a budget owner: Which templates carry watermarks or anchor images? Do update tests print real documents? Who checks printing after each update?
