If it is not visible, it does not.
ie: a DB25F is a bulky thing. 8^)

My workstation does not have visible DBxx ports (male or female), but there is an available header on the MB and a BIOS setting to activate a serial port.
I doubt that is the case with your laptop.

Now, even though there is no parallel port available to Linux, the line printer module (lp) is loaded at boot time, probably (?) by CUPS and as a result, the other printer modules. eg: parport, ppdev and parport_pc.

You could check with dmesg and lsmod to see if they are being loaded by any other software and eventually blacklist them if they are not needed.

Best,

thanks rolfie,

just that this laptop does not sport a parallel port, if am not mistaken.

maybe it is an error related to the printer (epson eco with ethernet, usb, wireless) instead.

will check some more.

From https://unix.stackexchange.com/question … rrupt-irq7
"Classically, the default usage of IRQ 7 is for the (essentially obsolete) parallel port (also known as IEEE 1284 or LPT)..."

Use the search machine of your least mistrust to find some more info.

maybe someone of you can tell me if i need to be concerned about it.

happened quite some time lately;
only hardware thing i did was changing the keyboard, but it seems function well so far.

thanks.
