i know turboprint is a very good option but the problem is for printers not supporting PS
I have a Epson R1800 and not PS supported.
Other and better way is contact with turboprint developers and asking for new versions or new printer drivers(in turboprint linux versions lot of modern printer drivers) i think now the amiga world have important market with classic systems and NG systems ,amigaos 3.9,morphos,Amigaos 4.1.x, usb 2.0 cards for classics.......
