Printing Directly To PDF Without Dialog

I found the following code which saves the contents of a NSTextView to
a PDF. This codde handles the paging and gives the user the standard
dialog asking where to save the file. I am wondering if I can save the
view (in my case a webView ) directly to a filename that I specify
without asking the user to name the file. Is this possible?


NSPrintInfo *printInfo;
NSPrintInfo *sharedInfo;
NSPrintOperation *printOp;
NSMutableDictionary *printInfoDict;
NSMutableDictionary *sharedDict;

sharedInfo = [NSPrintInfo sharedPrintInfo];
sharedDict = [sharedInfo dictionary];
printInfoDict = [NSMutableDictionary
dictionaryWithDictionary:sharedDict];
[printInfoDict setObject:NSPrintSaveJob
forKey:NSPrintJobDisposition];
[printInfoDict setObject:[sheet filename]
forKey:NSPrintSavePath];
printInfo = [[NSPrintInfo alloc] initWithDictionary:
printInfoDict];
[printInfo setHorizontalPagination: NSAutoPagination];
[printInfo setVerticalPagination: NSAutoPagination];
[printInfo setVerticallyCentered:NO];
printOp = [NSPrintOperation printOperationWithView:textView
printInfo:printInfo];
[printOp setShowPanels:NO];
[printOp runOperation];

Thanks for any help...

I don't know why it would not work, but for a WebView, you don't print the
WebView itself. You print [[[WebView mainFrame] frameView] documentView].
And you must wait that the WebView had load the request before sending the
runOperation message. For this use the webView:didFinishLoadForFrame: method
of the WebFrameLoadDelegate.

Personnaly, I used it only for simple web page without frame (HTML frame)
until now. I heard it can be a little more complex otherwise.
