Inkjet printer, and control method of an inkjet printer

A method of controlling an inkjet printer for printing labels, the method comprising:

• receiving, from a host computer, print data for images to be printed on the labels;
• receiving, from a sequencer, a first signal indicating a timing to execute a printing operation that includes printing the images, and a second signal indicating a timing to execute a predetermined operation that cannot be executed in parallel with printing the images;
• rendering the print data and executing the printing operation based on the rendered print data at a timing based on the first signal;
• and
• executing the predetermined operation at a timing based on the second signal.

A printing system comprising:

• an inkjet printer configured to print labels;
• a host computer configured to generate print data for images to be printed on the labels;
• a sequencer configured to send a first signal indicating a timing to execute a printing operation that includes printing the images, and a second signal indicating a timing to execute a predetermined operation that cannot be executed in parallel with printing the images;
• wherein
• wherein the inkjet printer comprises:
• a first interface configured to receive, from the host computer, the print data for the images to be printed on the labels,
• a second interface configured to receive, from the sequencer, the first signal and the second signal, and
• a controller configured to:
• render the print data received via the first interface, and execute a printing operation based on the rendered print data at a timing based on the first signal received via the second interface, and
• execute the predetermined operation at a timing based on the second signal received via the second interface.
