Epson Printer Offline

[pixellip]

HiI've shared two Epson inket A3 printers via USB. Apparently Epson don't support this on macs. One printer stays online but the other one goes off. I moved the printer to another mac and the problem still occurs. The printer is staying online on the mac it is connected to but on the other macs it appears offline. When you remove and re-add it it stays online.The powers settings on each mac are the same. I've set them to not sleep. The drivers are the same version.I can't spot any difference between these macs as they all all imaged the same.Can anyone please suggest anything else to try? I can't send them back and they weren't cheap.Thanks. Edited April 20, 2018 by pixellip
