RE: 'Can Anyone tell me of any Printers that can print on thicker paper?'

I have an Epson stylus R300, it has the facility to change the setting to thicker paper, however it ignores it and won't work with thicker paper. I agree with Doug Sinott, why have different ink cartridge designs? I suspect the answer is as follows: it can only be for the benefit of Epson, they want you to buy more inks!
