I have an old machinery that does some analysis and print out the results on an Epson LX300, connected via a serial port 25 pin.
Is possible to connect this machinery to a computer in order to digitalize the analysis results directly, emulating the printer?

It's certainly possible if the computer has a 25-pin serial port. I once did a database migration by printing the entire database to a computer over a serial link, capturing the output to disk, and then parsing the data into the new database. I believe that USB to 25-pin-serial adaptors are available.

Do I need any supplementary hardware between the machinery and the pc/usb adapter like a null modem adapter? – Nicola – 2017-11-15T11:43:26.100
@Nicola It's decades since I did much fiddling with serial connections, but you might need a null modem -- it depends how the serial ports on the printer and PC are wired. – Mike Scott – 2017-11-15T11:44:35.257
