Please ask whether node escpos supports parallel port LPT communication printing? Or node escpos does not support parallel port LPT. Is there an alternative? about node-escpos HOT 3 OPEN

I got the same problem

from node-escpos.

I had the same problem : for some old printers, there is some stupid rules which give the same VID/PID to the 2 interfaces of the printer, so the package is not able to find which one is for power supply / firmewire update and which one is for the actual escpos communication.

there is no solution, because it's at the binary level of the usb package : libusb does not support that.
it give us the flag at the interface level which identify the 2, but it's unusable 'cause the call is on VID/PID

so, you have to install a software which emulate properly new 2 different VID/PID (my choice) for these interfaces, or by a more recent printer which has 2 different VID/PID

I found this one, it works for me
