Viscosity modulated dual feed continuous liquid ejector

A method of printing comprising:

• providing a continuous liquid ejector including:
• a structure including a wall defining a nozzle, the nozzle having a fluidic resistance R1;
• a first liquid feed channel in fluid communication with the nozzle, the first liquid feed channel having fluidic resistance R2;
• a first drop forming mechanism associated with the first liquid feed channel;
• a second liquid feed channel in fluid communication with the nozzle, the second liquid feed channel having a fluidic resistance R3, the fluidic resistance R1 being less than the fluidic resistance R2 plus the fluid resistance R3 (R1<(R2+R3));
• and
• a second drop forming mechanism associated with the second liquid feed channel;
• providing liquid under pressure sufficient to eject a liquid jet through the nozzle of the continuous liquid ejector;
• simultaneously actuating the first drop forming mechanism and the second drop forming mechanism to cause a portion of the liquid to break off from the liquid jet and form a liquid drop.
