Sideband signal for fluid ejection

A system, comprising:

• a print media;
• a fluid ejection system to print a line of an image on the print media;
• and
• an inspection system to analyze the line of the image on the print media and determine a respective amount of time delay for a plurality of fluid ejection devices within the fluid ejection system, wherein the respective amount of time delay is inserted into at least one sideband signal to provide a correct alignment of the plurality of fluid ejection devices when printing a subsequent line of the image on the print media.

A method, comprising:

• printing a line of an image on a media via a plurality of fluid ejection devices of a fluid ejection system;
• determining a respective amount of time delay for each one of the plurality of fluid ejection devices based on an analysis of the line of the image on the media such that the each one of the plurality of fluid ejection devices is correctly aligned when a sideband signal is received;
• inserting the respective amount of time delay for the each one of the plurality of fluid ejection devices that is determined into the sideband signal for printing a subsequent line of the image on the media;
• transmitting the sideband signal to the plurality of fluid ejection devices with the respective amount of time delay;
• and
• printing the subsequent line of the image on the media via the plurality of fluid ejection devices using the sideband signal with the respective amount of time delay.
