How to determine which protocol printer is using?

[fessen]

I have a wireless network printer. How do I tell which protocol(s) the printer needs for simple print jobs?

I noticed that a long list of different protocols are enabled. I would like to disable the protocols that are not really needed. For example, I don't think the printer really needs POP3/SMTP enabled.

----------

(I realize I could try disabling all the protocols and then re-enabling each of them one by one, but I hope there is a more efficient way to find the answer!)

Exactly what printer is it?

Your quest is a complete and total waste of time. Protocol support is built into your printer's firmware. Network printers are designed to use multiple protocols simultaneously while accepting jobs from multiple devices on the LAN.

For a printer behind your router, then there is no need to futz with access. If multiple devices can see your personal printer, then you may limit access to conserve toner, paper, and wear and tear. However, some mythical or imagined "efficiency" is not an issue.
