I have created a Processing screen, To process EMAIL and PRINT of multiple Payment and Application documents.

While Processing PRINT I am getting the following ERROR. [enter image description here][1]

The Screen ID showing in the error message is the report screen ID which should pop up to print the report. but the Report is not popping up.

[enter image description here][2]

We are getting error in line no 72, throw ex;

I am unable to find out where I am going wrong,

It looks like the code snippet you showed is of ARPaymentEntry graph extension however you also mention that it is a custom processing screen. If you have added this action to the Payments screen, then try the below code snippet. You could use one of the overrides of PXReportRequiredException method as needed.

public PXAction<PX.Objects.AR.ARPayment> PrintReceipt;

        [PXButton(CommitChanges = true)]
        [PXUIField(DisplayName = "Print Official Receipt")]
        protected IEnumerable printReceipt(PXAdapter adapter)
        {
            Base.Save.Press();
            string reportID = "AR302070";
            List<ARPayment> list = adapter.Get<ARPayment>().ToList();
            int i = 0;
            Dictionary<string, string> parameters = new Dictionary<string, string>();
            foreach (ARPayment payment in list)
            {
                parameters["PaymentType"] = payment.DocType;
                parameters["PaymentNbr"] = payment.RefNbr;

                i++;
            }
            if (i > 0)
            {
                throw new PXReportRequiredException(parameters, reportID, string.Format("Report {0}", reportID));
            }
            return list;
        }
