Abstract: A printing system triggers the print head of a conventional printer cartridge configured per se for water-based printing ink. The printer cartridge print head includes ink ejector elements arranged in a matrix and a heating element of an ink ejector element that is activated by use of an address signal functioning as a line signal and by use of a master signal functioning as a column signal. The master pulses of the master signal have a lesser signal amplitude than the address pulses of the address signal (AS1). The printing ink in the printer cartridge has a high proportion of alcohol.
