Printing system comprising at least one apparatus for applying a design to at least one fingernail/toenail surface, which apparatus comprises: - means for positioning at least one fingernail/toenail surface, - an optical device, - a print head, - means (2, 2c, 3) for displacing the print head in order to apply a design to the fingernail/toenail surface, - a control unit incorporating: ∘ a means for communicating with the optical device, ∘ a computer application comprising instructions for controlling the displacement means (2, 2c, 3) according to the design, so as to direct the print head in order for it to apply said design to the fingernail/toenail surface, being characterized in that: - the optical device is configured to acquire an image of the fingernail/toenail surface, - the instructions included in the computer application of the control unit are also adapted to control the displacement means (2, 2c, 3) according to the image of the fingernail/toenail surface acquired, - the system further comprises: ∘ at least one server remote from the apparatus, which server incorporates at least one database in which digital data are stored, ∘ a series of terminals (6a, 6b, 6c, 6d) belonging to a community of users, each said terminal incorporating at least one means for generating a design in the form of digital data, each said terminal also comprising a means for communicating, via an Internet network, with the remote server, so that said data generated are transmitted to said remote server, - the remote server incorporates a computer application comprising instructions for storing the received digital data hierarchically, said data being stored in memory areas (5a, 5b, 5c, 5d) of the database, which memory areas are associated with each of the users of the community and are accessible by password and/or identifier, - the control unit takes the form of a touch tablet removably connected to the apparatus, which tablet comprises a means for communicating, via an Internet network, with the remote server, so that said tablet can access at least one of the memory areas (5a, 5b, 5c, 5d) and download the digital data which are stored therein, which downloaded data correspond to the design to be applied to the fingernail/toenail surface. -
