Hard to say. Once the printer is fully operational, it will only be a matter of testing.

I have all the printer code available from the HP-97 project, and it simulates ok, but in the real world there are probably differences required because of the smaller 19C paper size. I will have to try it out as soon as I can and adjust things accordingly.

I am also concerned about the printer if people operate the 19C on 4 x 1.5V batteries. The 19C was designed to run from 5V, not 6, so this may affect operation. I have a high current series diode in line with the battery which can be bypassed for 5V, or not for 6V.
