As of this writing, the PrintPlugin from the GitHub repository is targeted at Cordova 1.5. If you get that version, and make the following changes, you can compile within a Cordova 2.0 Project.

NOTICE: I have seen a bug in this entire plugin which is an issue with printing more than one page. I have found that it is related to a lack of logic to wait for the webView to complete load before printing. I am currently working a a new version of this plugin to allow for custom headers, page numbering etc. But for now..... ;)

In the current repository .m file, it has the following function declaration:

- (void) print:(NSMutableArray*)arguments withDict:(NSMutableDictionary*)options{
    NSUInteger argc = [arguments count];

    if (argc < 1) {
        return; 
    }
    self.printHTML = [arguments objectAtIndex:0];

  ... << snipped />> ... 


    [self doPrint];
}

This is followed with a separate doPrint function.

- (void) doPrint{
    if (![self isPrintServiceAvailable]){
        [self callbackWithFuntion:self.failCallback withData: @"{success: false, available: false}"];

        return;
    }

    UIPrintInteractionController *controller = [UIPrintInteractionController sharedPrintController];

      if (!controller){
          return;
      }

        ... << snipped  (cut and paste to below) />> ...
}

I updated my local copy and merged the two into a single function, and utilized a different mechanism for obtaining the arguments. Following is my .m function declaration:

- (void) print:(NSMutableArray*)arguments withDict:(NSMutableDictionary*)options
{   
    // NSUInteger argc = [arguments count];

    NSString* printHTML = [options valueForKey:@"printHTML"];
    NSString* successCallback = [options valueForKey:@"success"];
    NSString* failCallback = [options valueForKey:@"fail"];
    NSString* dialogLeftPos = [options valueForKey:@"dialogLeftPos"];
    NSString* dialogTopPos = [options valueForKey:@"dialogTopPos"];


  UIPrintInteractionController *controller = [UIPrintInteractionController sharedPrintController];

  if (!controller){
      return;
  }

    ... <<  snipped (paste the rest from your original block here />> ...
}

I then also modified the .JS to create an object instead of simply the parameter list.

The current repository PrintPlugin.js has:

return Cordova.exec("PrintPlugin.print", printHTML, callbackPrefix + '.success', callbackPrefix + '.fail', dialogLeftPos, dialogTopPos);

return Cordova.exec("PrintPlugin.print", printHTML, callbackPrefix + '.success', callbackPrefix + '.fail', dialogLeftPos, dialogTopPos);

I changed this to the following:

var args = {
    'printHTML': printHTML,
    'success': callbackPrefix + '.success',
    'fail': callbackPrefix + '.fail', 
    'dialogLeftPos': dialogLeftPos,
    'dialogTopPos': dialogTopPos
};

cordova.exec(null, null, "PrintPlugin", "print", [args]);

Now, it may turn out that I could have simply changed the case in the Cordova to cordova, but that is pure hindsight. Either way, I hope this helps!
