It depends on what you want/need. I have (not as a print server, but as firewalls/poorman's NAT's) used successfully old thin clients, typically they use a fraction of the power of any old desktop, exception made - maybe - for some early mini- or micro-itx machines. In case this is an excellent resource: https://www.parkytowers.me.uk/thin/index.shtml https://www.parkytowers.me.uk/thin/index.shtml But a number of (now obsolete) home routers (the kind the ISP provides and never asks back for after a couple years), have a print server included (with a USB port), that could be even easier/lighter, of course with less features than an even small box running a Linux or similar.
