Hi Michal,

Definetely this ML should be read at least by czech people. Others are welcome
for sure. Thanks a million for your translation and re-explanation.

I am going to test in that way tomorrow. Of course, I still do not understand
why I cannot print directly with > /dev/lpt0.

About acpi, I told that because I have ppc0: <Standard parallel printer port>
port 0x378-0x37f irq 7 on acpi0 in dmesg and all the examples I saw had isa
instead of acpi. Any idea? Is it normal?

Thanks again Michal.

Regards, Ivan
