SP300E

Hi. I have come in possession of a SP300E printer, without power source.
Before I am going to buy a 5V 2,5A adaper, I am going to ask:
Is this printer usable without specific drivers or servers?
I am willing to connect it to a router.
Will it work as a generic (albeit limited in size) printer or is it "invisibile" but for Zyxel servers?

Thank you in advance.
