Hi and thanks

the problem is: I do not know how to get the VendorID:ProductID of the parallel port devices.

No, Is not in lspci or lshw.

there are only devices connected on the board, and on the usb but not the connected on lpt (parallel) port.

And the printer is connected using the parallel port

Try:

dmesg | grep parport

dmesg | grep parport[\code]
[i]none output[\i]

[p]and with:[\p]
[code]dmesg | grep lp[\code]
[p][i]output:[\i][\p]
[code]
[   14.316205] lp: driver loaded but no devices found
[   14.644475] lp0: using parport0 (interrupt-driven).
