Processing version

Operating system

Windows 11 Professional

Bug description

When I open Processing 4.5.2 on Windows 11 Professional and I press "File" -> "Print", the application proceeds to freeze for some extent of time (1 - 2 minutes). The bug only happens the first time I press print after opening Processing, once it has happened I can press print and the dialog opens like normal. The desktop computer I use has had printer connections in the past, 5 to be percise, and only one of them is a physical device. The others are things like "Microsoft print to PDF", or "Fax". I have tried recreating this issue on my laptop by removing all printers and scanners but had no sucess. Though, I can consistently recreate the issue on my desktop without failure.

Steps to reproduce this

You need:

Windows 11 professional
A computer with a printer connection that is not in range.
-My specfic printer is a HP OfficeJet Pro 8020 series, with a Microsoft IPP Class Driver.
Processing 4.5.2

Steps:

  1. Open a fresh processing application

  2. In the newly created file click - File -> Print

  3. The application will freeze (fully unresponsive) for about a minute until the file dialog finally opens

调研方向

从 PDE File -> Print 入口开始,在 Windows 11 上使用无法访问的打印机连接,重现首次使用时的卡死问题。跟踪初始打印对话框需要 1–2 分钟才能打开的原因,然后验证对话框在第一次尝试时即可正常打开,且不会导致后续打印出现回归问题。
