Print remotely via internet and without computer

Hello,

To communicate with a receipt printer (POS):

  • With a serial port: we could send ESC / POS commands
  • With a USB (or other) port: we could directly send files (eg PDF) to the driver
  • With an Ethernet port: we can use the driver. But if the printer is connected directly to the internet router without a computer, can we send (via internet) a PDF file directly to the printer? Or using ESC/POS commands is mandatory?

(Epson sells printers dedicated to it. But the customer must buy a new printer, I would prefer that this is not the case.)

Thank you
Olivier

Any conventional router is passing your printing information to the printer without any translation. Unless your printer understands PDF, you’ll need to speak a language it does understand.

With the ethernet connection, you still have a driver at the local end that translates what you give it to the printer’s language. Think of the ethernet connection as a really long invisible USB cable.
