Abstract
Description
Technical Field
[0001] This application relates to the field of printing equipment technology, and more specifically to a thickness-adjustable printing controller. Background Technology
[0002] With the development of printing technology, batch printing is now required to increase printing speed, necessitating the control of multiple printing devices by multiple print controllers. A print controller typically consists of a housing and an internal print driver circuit board. The complexity of the print driver circuit board varies depending on the specifications of the print controller, resulting in different thicknesses for the same size. Therefore, housings of varying thicknesses are needed to mount these different thicknesses of print driver circuit boards. To reduce housing production costs, it's necessary to use housings of uniform specifications for assembly. This requires providing suitable mounting space for print driver circuit boards of different thicknesses. However, current housing specifications are standardized. Therefore, how to rationally design the housing to accommodate print driver circuit boards of varying thicknesses has become a pressing technical problem to be solved. Summary of the Invention
[0003] This application provides a thickness-adjustable print controller, which solves the technical problem that it is difficult to adapt to print drive circuit boards of different thicknesses when using a uniformly sized shell to assemble the outer shell of the print controller, and the need to set different sized shells, which increases the production cost.
[0004] This application provides a thickness-adjustable printing controller, including:

Furthermore, front and rear baffles are provided to cover the front and rear end side plates of the first and second housings while exposing the electrical interfaces to ensure normal operation.
