Abstract
The present invention relates to a method for determining survival state of a print head. The cleaning behavior of a print head can be used for reflecting health status of the print head, so survival state of a print head can be determined according to cleaning behavior of the print head. Specifically, a method is implemented for determining survival state of a print head, comprising: obtaining cleaning behavior data and cumulative printing amount upon failure occurrence of print head(s) of reference printer(s) as well as cleaning behavior of a print head of a current printer; obtaining printing amount of the current printer; determining survival state of the print head of the current printer according to cleaning behavior data and cumulative printing amount upon failure occurrence of the print head(s) of the reference printer(s) as well as cleaning behavior data and printing amount of the current printer.
