How to organize color printing at the enterprise?

Question

Seal

There are 2 printers Epson l800 and l805 they do not have ethernet interfaces, only usb. Now they are connected to the machine and shared from it to 6 computers. But it all works clumsily: printing takes a long time (because a 100-megabyte layout from Photoshop crawls to the printer for a long time), sometimes they disappear offline (I don’t know it), and plus, on each PC, you need to configure print settings and color profiles. Does anyone have experience in organizing the work of a small print department?
