Status: RESOLVED WONTFIX

(Core Graveyard :: GFX: Mac, defect)

In my extension, I try to enumerate all printers through
nsIPrintOptions.availablePrinters, but such exception is thrown on Mac OS X.

[Exception... "Component returned failure code: 0x80040154
(NS_ERROR_FACTORY_NOT_REGISTERED) [nsIPrintOptions.availablePrinters]" 
nsresult: "0x80040154 (NS_ERROR_FACTORY_NOT_REGISTERED)"  location: "JS frame ::
chrome://catcher/content/printerdialog.js :: onLoad :: line 10"  data: no]

The same code works on Linux/Windows XP

Also, if printing to file does not works on
Mac(nsIPrintSettings.printToFile=true).Even it I set current nsIPrintSettings to
printToFile and toFileName, the output still is sent to printer instead of file.
 But the same code works well on Linux/Windows XP.  


Reproducible: Always

Actual Results:  
Exception thrown. 
[Exception... "Component returned failure code: 0x80040154
(NS_ERROR_FACTORY_NOT_REGISTERED) [nsIPrintOptions.availablePrinters]" 
nsresult: "0x80040154 (NS_ERROR_FACTORY_NOT_REGISTERED)"  location: "JS frame ::
chrome://catcher/content/printerdialog.js :: onLoad :: line 10"  data: no]

Expected Results:  
availablePrinters() and printToFile works on Mac OS X, just as Linux/Windows XP.

Mac doesn't have a class for NS_PRINTER_ENUMERATOR_CID

Note that a lot of the printing stuff is not really implemented on mac from what I can see, since a lot of it is handled by the OS instead.

Filed bug 675709 on the printToFile issue.

[Zack Weinberg (:zwol)]

I am WONTFIXing this because the "modern" printing APIs on OSX (and all other supported platforms) strongly discourage enumeration of all available printers, and accordingly, nsIPrinterEnumerator (which replaced nsIPrintOptions.availablePrinters) is being removed in bug 629500.
