Printing Checks from Oracle Cloud SaaS to Local Internal Printers

From a Network Architecture standpoint, I have the following questions regarding Oracle Fusion check printing:

Essentially, we are trying to eliminate the need to expose printers to the Internet.

1. What network connectivity options do you typically recommend for customers who need Oracle Fusion to print to on-premises printers over the internet?

2. Do you have integrations with third-party providers that enable check printing within a customer's environment?

3. Can you provide the list of CIDRs that Oracle Fusion Services will use to initiate the printing process?

4. Does Oracle SaaS Fusion support integration with a customer's print spooler instead of the printer itself?
