A printing system holds a plurality of content data and linking information which links a printer and registration information of a user registered to an SNS. When a posting including content data identification information is performed to the SNS, the printing system judges the presence or absence of linking of the registration information of the user who has posted and the printer by referring to the linking information. When there is a printer linked to the registration information of the user who has posted, the printing system acquires content data identified by the identification information included in the posting from the content data holding unit, generates print data for printing an image from the content data, sends the print data to the printer linked to the registration information of the user who has performed the posting, and causes the printer to print the image based on the print data.
