Discontinued. I'm still debating selling mine since I think I'm the only person who doesn't like it (bad color gamut). The Staples in my area still has one way up in the storage racks around the outer wall of the store next to the Electronics department. I'd buy it and resell it but I don't use PayPal.
The Stylus Photo 1400 is also discontinued. The replacement Artisan 1430 is very similar to the 1400. The replacement for the Workforce, however, is the WF-7010 that has a bottom feed tray. This concerns me because I think it will be more prone to paper jams, and I don't know how on earth you would print banners/rolls of material now.
