EPSON LQ-590IIN Ethernet

Printer set to DHCP so had to find it's IP address.

Using NMAP on PC terminal:

{{{
nmap -T4 -F -oN C:\temp\scan_q.txt 10.1.0-5.*

…

Nmap scan report for 10.1.5.123
Host is up (0.00034s latency).
Not shown: 95 closed tcp ports (reset)
PORT     STATE SERVICE
80/tcp   open  http
443/tcp  open  https
515/tcp  open  printer
631/tcp  open  ipp
9100/tcp open  jetdirect
MAC Address: DC:CD:2F:C6:15:E3 (Seiko Epson)
}}}

…

For production environment you would need to set printer to use a static IP or setup your router/DHCP server to always assign the same IP address based on the printer's MAC address (static DHCP)

Make sure "Allow RAW(Port9100) Printing" is checked.

825 may make a network client connection on Port 9100 to the printer's IP address and send text data to printer. The printer buffers data received until a (form feed) character is received. The CCommClient class in lib825ev may be used for TCP/IP communications as a client [wiki:Docs/Prog/Manual/ApplicationLibraries/lib825ev/Comm/CCommClient CCommClient]
