I have set up my TL-PS110U print server connected to my windows 10 device via wired ethernet router. The print server is connected via USB to Samsung SCX 4100 printer. I set up a new printer a new network printer with manual settings, creating a new standard TCP/IP port with custom setting using LPR.

I've used the same driver when connecting directly to the USB printer (Samsung Universal Printer Driver).

When I attempt to print to the printer via this network printer, the printer warm up is initiated and the LCD on the printer sayas printing....but doesnt. So  it seems that the printer is recognised (can also PING OK) but when it comes to sending the data and actually priny, something goes wrong.

Any suggestions?
