I am new to the forum. I have been printing with Piezography ink sets first in a 4000 and later in a 9880 for about 8 years. I recently acquired an 11880 for and I would like to install Carbon K7 in it. Getting cartridges that work seems to be a pain, but I am confident that inkjetsolution.eu can make it work for me. So far I have not put any ink in the machine. Before I do, I would like to ask if anyone here has had success working with 11880 and Piezography K7 either with QTR or Studioprint and which workaround worked. I used to treat my 9880 as a 9800 in Studioprint in order to get access to the monochrome mode, would this be possible with the 11880 as well?
