If this Epson is the FX-2175 dot matrix printer from your other threads, you can likely use the default Windows ESC/P 9 pin V4 Class driver from Windows 2012.
Epson EscP/2 – used in some serial printers and older inkjet printers from Epson.
Epson Esc/Page – used in many Epson laser printers.
Epson Script – used in some Epson laser printers.
Printing PDF/bitmapped reports directly to a dot matrix printer will require extra setup because Pasta normally converts PDF to Postscript which the Epson does not understand.

I have seen evidence of people getting this working on dot matrix printers.
Does this mean that the one you setup using a laser printer will not work on dot-matrix?
No. It means you would have to copy printer types and styles making Epson specific version with specified printer initialization strings from the notes in order to print PDF to Epson dot matrix printers. The steps from the notes have nothing to do with any other laser printer configurations you may have executed.
