Print escape codes to wifi printer

[JosepM]

Hi folks,

I would like to know how can I print or send escape codes to a printer.
The printer is a receipt printer connected via wifi.

Thoughts?

Salut,

Hi,

Googling I found that I need to use ESC/POS commands to send to the printer, I haven't clear the port. I found that I must use the port 9100 and in others the port 515.

Any idea?

Salut,
Josep
