How to have print box close automatically?

I don't have this problem myself, but I would like to find out what is going on. If you meet this problem constantly, please reproduce the poblem, then press all five keys at the same time, <control>-<option>-<command>-<shift>-<.> (period key), wait a couple of minutes, you should get a file whose name starts with "sysdiagnosis". Please then share that file here, that might give us some useful information about what is going on.

Hi Pengtao, thanks for your interest. Please don't take this the wrong way, but my sysdiagnose file does contain information that I'd prefer to not share with the whole world, so I don't think I'll post it here 🙂

In any case, I can recreate this problem (printer proxy does not quit after print job completes) 100% of the time, all I have to do is print something, from any program, and the printer proxy simply stays open until I manually quit it.

Do you by any chance also have Default Folder X or Dropbox installed? Does this problem go away if you disable them and reboot the computer?

Good find pengtao. Here we were thinking it was something in the core system when it was a third party application all along.

I noticed that the other posts with the same issue also were using this Default Folder application. How did you find it could be the cause? Especially since none of the users mentioned using this app at any stage until you asked.

Hi Pahu, I happened to know a person who inspected a live case and finally solved it by trying all sorts of different things.

Exclnt. Thx for the reply.

Thanks Steve, I'm looking forward to turning DFX back on, I miss it 🙂

I was having the same annoying problem. The ~/Library/Preferences option didn't work for me and I too was confused when I couldn't find anything names Proxy when I opened ~/Library/Printers. BUT I did see a IntalledPrinters.plist file that was just in the folder, not in any specific printer folder. I wasn't sure what would happen, but I recalled the plists are auto-regenerated so I felt safe (OK, partly safe and still nervous) and I deleted it Then I went to print a page and presto, the printer icon autoclose as soon as the page finished printing. Oddly, that plist file doesn't reappear, at least not where it was, so maybe a hangover for Lion days that was causing problems not with the Lion is on the Mountain. Don't know, put my Dock is now happy (OK, I'm the one who's happy that my Dock is not retaining an open printer icon).
