Thanks again Brian!

Well, actually I had found this:

What is your parallel port configured as in your BIOS?

Go into your system BIOS (follow your system documentation) and check
that your parallel port is configure for ECP mode.

But since my machine (HP Compact dx2400 Microtower) didn't come with a
parallel port, there's nothing about that in the Bios.

I've myself added a small card with such port:

---

03:00.0 Parallel controller: NetMos Technology Device 9900 (prog-if 03
[IEEE1284])
        Subsystem: Device a000:2000
        Flags: bus master, fast devsel, latency 0, IRQ 5
        I/O ports at dc00 [size=8]
        I/O ports at d880 [size=8]
        Memory at feaff000 (32-bit, non-prefetchable) [size=4K]
        Memory at feafe000 (32-bit, non-prefetchable) [size=4K]
        Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+
        Capabilities: [78] Power Management version 3
        Capabilities: [80] Express Legacy Endpoint, MSI 00
        Capabilities: [100] Virtual Channel
        Capabilities: [800] Advanced Error Reporting

But how could I verify whether or not it is "in ECP mode"? How would I
configure that card? Shall I look for a "swith" on the motherboard?

Beside, the same card with the same printer and the same cable worked
under xp.
