Total Sales Amount 1000
User Paid Amount 500
Currently System allow user to Submit

add code like this

this.$component.on('click', '.submit-order-btn', () => {
			const doc = this.events.get_frm().doc;
			const paid_amount = doc.paid_amount;
			const items = doc.items;
			const out_stand = doc.outstanding_amount
			if (paid_amount == 0 || !items.length) {
				const message = items.length ? __("You cannot submit the order without payment.") : __("You cannot submit empty order.");
				frappe.show_alert({ message, indicator: "orange" });
				frappe.utils.play_sound("error");
				return;
			}
			if (out_stand > 0){
				const message = __("You cannot submit the order with  Outstanding payment.")
				frappe.show_alert({ message, indicator: "red" });
				frappe.utils.play_sound("error");

@santhida
this will only set discount to 0 for new invoice not refresh that field
apps/erpnext/erpnext/selling/page/point_of_sale/pos_controller.js

		make_sales_invoice_frm() {
		const doctype = 'POS Invoice';
		return new Promise(resolve => {
			if (this.frm) {
				this.frm = this.get_new_frm(this.frm);
				this.frm.doc.items = [];
				this.frm.doc.is_pos = 1;
				this.frm.doc.additional_discount_percentage = 0;
				resolve();
			} else {
				frappe.model.with_doctype(doctype, () => {
					this.frm = this.get_new_frm();
					this.frm.doc.items = [];
					this.frm.doc.is_pos = 1;
					this.frm.doc.additional_discount_percentage = 0;
					resolve();
				});
			}
		});
	}
