Zebra 105 Se label printer with serial interface needs to connect to the network. Have used Milan MIL-P3830 print servers, which have RS232 ports, but cannot find any print servers now with serial ports. I tried an IOGEAR print server with USB output, and connected it to the printer with a USB-to-DB25 RS232 adapter cable, but it did not work. I suspect the adapter cable is desiged to be connected to the USB port of a PC, and that the print server's USB port is not providing the power needed for the RS232 interface. I wonder what the experts think, and if they have any suggestions for this project. The only solutions I can think of now are: buy a new printer with USB interface; or try to find a used print server with the serial ports. The interface on the 105 Se cannot be replaced with USB or Ethernet.
