I have no clue about the ink, but I do agree with the external waste ink tank. It's more like a reminder for myself to dump that before it overflows! LOL And yes, my t2 came with the bulk ink pre-installed, and $1000 off of MSRP & about 1500 of free accessories. That was hard to resist. I'm already eye-ing the jumbo2 if things go well.Here is my pros for the t-jet
-inks when printing white- the kiosk uses a dupont white ink while using R&H for colors. dupont whites do not work as well with R&H colors as they do with native dupont colors. Not saying that the Kiosk cant print nice looking dark shirts because it can but the Tjet uses dupont white along with dupont color.
-Waste ink tank is better placed on the tjet, and external waste ink tank lets you keep an eye on the levels while seeing if you head cleanings are actually working.
-if you buy a tjet now it comes with a factory installed bulk ink system
-amazing RIP- works great with photoshop and any other design program I throw at it.
