@ Cristian - no problem

I agree about laser printers waiting unitl a FF (form feed) is received. They normally buffer a whole page, because they print it in one go.

Oh, sure! It's simply logical! I feel a bit silly
Indeed yesterday I printed a long directory and the first page exited automatically. I'm really a "Rom dongle"
Anyway, my interface can accept only 9600 Baud, am I right?

Thanks

Yes, according to the manual (http://www.dilwyn.me.uk/docs/manuals/QL ... Manual.pdf ) it's fixed at 9600 Baud. And I wouldn't worry too much about that because most programs will not even be able to send at higher speeds anyhow on the standard QL.

Yes I read the manual; but since it seems very old, I thought it could be a matter of ancient Roms or old software restrictions. In any case, this speed for me is more than satisfactory

Now I can say that my interface is officially resurrected!

Thank you very much

The speed is set by two things:

• the highest speed the QL serial system can manage reliably
• the hardware of the interface is fixed at a single speed (hence why it works with two "simple" logic chips instead of a more expensive UART)

Also keep in mind that at the time, the two common types of printer were 9 pin dot matrix and daisywheel types, neither were that quick, so 9600 bps was more than enough

Thank you Mark for your useful information
