A printer having at least first and second print heads, each with independently controllable print resolution, controllably prints text data with a first resolution and non-text data with a second resolution. Preferably, the printer is comprised by first and second ink jet print heads which eject ink droplets through plural nozzles based on digital data stored in a print buffer. Resolution is controlled by controlling ink droplet size, nozzle ejection sequence, and readout order from the print buffer, all with droplet size, ejection sequence and readout order being controlled independently for each print head. A user interface allows a user to control resolution of text and non-text data independently.
