My understanding is that this is not the case. MiNT is rerouting the printer related GEMDOS calls to the lp device internally.

At least I was able to print from QED (using its GEMDOS print routines) and Teradesk (dropping a text file to the printer icon) using the modified driver (on top of an unmodified EmuTOS that won't allow to print itself).
