QT-6000 Receipt Printer

Hi all,

I've got an old Casio QT-6000 terminal, which I'm trying to get to work with a receipt printer (namely, a SNBC BTP-R580II) over RS232 on COM6.

I'm assuming this isn't working, because this printer isn't compatible with the QT-6000 perhaps?
I've set everything up in I/O Params (Printer 1, 2, and 3) with the 6103 value for each printer (I've also tried 6102, just in case), and I've set the printer up as configured in the Printer Connections menu, but everytime I try and print, I get E061.

Is this down to the fact that the printer isn't supported, or is it me doing something stupid? I'm happy to buy a compatible printer if it's a compatibility issue.

Thanks,
Oli
