Hi Michael,

I have to make a workaround for this, since there is no button on printer.

We just take into consideration in the case that filter running on the same system as user.

My plan is to call an external application in filter with LSOpenApplication API. When user click the button on the external application, triggered the job left.

Any suggestion is appreciated.

Thanks
