I’m trying helping my dad resolve a printer issue. On his Epson ET-5850, if he sets a static IP to say 192.168.168.x, after a few pages of printing, the printer changes the IP address back to its default of 10.1.1.x. Then, the printing stops until set back to my dad’s IP range of 192.168.168.x. Anyone know whey this is happening? Thanks.
