Digital BW, The Print

Hi Paul,
I hope you could help clarify some confusuion that I have.
I read on your website that the 1270 is not recommended for glossy
printing.    Is it because of the fact that it cannot print at 
2880dpi or some other reason?  I mostly print from Photoshop 7,
currently own a 1280 and seriously thinking about getting a second 
printer for B&W.
regards, Opus
