RE:  Printing contest QSO info directly onto QSL cards

I can print log/qso info on labels till the cows come home....

But I'd like to print the info directly onto the QSLs.
Is there some sort of special printer or paper feeder for this?
I can't imagine printing 1000's via the "10 at a time" method.

Thanks,
