I have a toshiba windows vista and have tried multiple times to download a driver for the riso rp 3105 model , and from their site I believe to download the correct one but can't seem to send my printed file to the riso. either it says the printer is offline, even though I'm connecting with a usb. Any Advice? the computer shows the riso printer and the driver seems to have worked, but whenever i hit print, it goes to the printer queue but then nothing after.
