Digital BW, The Print

Austin,

If it is a printer hardware limit, how do you explain that (according to
Epson) the 3000 will print to 227" from Adobe Illustrator and 1800" from
Coreldraw. Also that in MacOS and 98/ME the 7500 has a limit of 90.5, but in
NT/2000/XP the limit is 590.5? The 3000 has the same limits for each OS!
