问题
I have been given a screenshot from a web page which shows the list of all installed printers accessible by the client (local and network ones) in a combobox and let user select one. Even there is a button to refresh the list!
I do not have access to the page and cannot prove the functionality. Is that even possible to do this or simulate this job by any means in a web page?
回答1:
If I had to hazard a guess, I'd say that it's most likely a list of network printers, retrieved via some server-side code. The "Refresh" button seems to back that up as there's obviously AJAX at play. Simply, though, there's no way to get this information client-side via JavaScript, so there's got to be something else going on.

You can use neodynamic's product. No ActiveX, no flash etc. only install small app on clien side(its free) but .net sdk or php sdk is not free.

Looks like it might be possible on Windows, but I'm not a Windows-guy so I can't evaluate this: http://www.codeproject.com/Questions/104211/How-to-get-the-client-printer-name-using-JavaScrip
