Inkjet printing has attracted wide attention due to the important applications in fabricating biological, optical, and electrical devices. During the inkjet printing process, the solutes prefer to deposit along the droplet periphery and form an inhomogeneous morphology, known as the coffee‐ring effect. Besides, the feature size of printed dots or lines of conventional inkjet printing is usually limited to tens or even hundreds of micrometers. The above two issues greatly restrict the extensive application of printed patterns in high‐performance devices. This paper reviews the recent advances in precisely controlling the printing droplets for high‐resolution patterns and three‐dimensional structures, with a focus on the development to suppress the coffee‐ring effect and minimize the feature size of printed dots or lines. A perspective on the remaining challenges of the research is also proposed.
