  • Patent number: 10093511
    Abstract: In printing processing, an MFP determines whether the number of printed sheets is less than or equal to an upper limit of bindable sheets of staple-less binding in a case where staple-less binding is set in print data. If the MFP determines that the number of printed sheets is less than or equal to the upper limit, the MFP determines whether binding processing is to be performed by switching to staple-less binding. If the MFP determines to perform binding processing by switching, the binding processing is performed by staple binding.
