I've noticed a behavior quite similar to this, on Ubuntu, as a result of the below-linked bug:
https://bugs.launchpad.net/bugs/1069671 In a nutshell: Running the CUPS 1.6.1 client locally, talking to a remote CUPS 1.5.x (or older) server. The client cannot communicate with the server, due to an IPP version mismatch, and fails to handle the error condition gracefully. In my case, it occurred when I attempted to print a Web page in Chromium. As soon as I hit Ctrl+P, the window in question no longer responded to clicks, scrolling, closing, etc. (Other browser windows continued to function, probably due to Chromium's multiple- process model.) The IPP version-mismatch issue was fixed in 1.6.2 (an explicit version specifier is now required for the CUPS client to work with older servers), but the behavior of the client in a server-related error condition almost certainly remains an issue. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
