A method comprising: by a print driver, obtaining from a remote repository of a linking service, a set of machine-readable links, with each of the machine-readable links being assigned in the linking service to a user account; intercepting, by the print driver, a print command within a print path of an operating system of a computing device, with the print command corresponding to the user account being issued in response to a request to print a digital document onto a print medium by the computing device; applying one of the obtained machine-readable links onto a portion of the digital document to be printed; generating a print format version of the digital document including the applied machine-readable link; storing the generated print format version of the digital document including the applied machine-readable link to a network accessible location over a communication network; and digitally rendering, on a display device, the print format version of the digital document including the applied machine-readable link and/or executing the print command so as to print, on a print medium, the print format version of the digital document including the applied machine-readable link, the method further comprising: by a linking service system executing at the network accessible location, detecting content present in the portion of the digital document; analyzing the content present in the portion of the digital document; obtaining content-specific information based on the analyzing; and linking the content-specific information with the applied machine-readable link, wherein upon linking, the machine-readable link is readable to provide access to the content-specific information using the communication network, wherein the linking comprises: determining a unique identifier of the machine-readable link applied onto the portion of the digital document; and mapping the unique identifier of the machine-readable link with the content-specific information corresponding to the portion of the digital document. by a print driver, obtaining from a remote repository of a linking service, a set of machine-readable links, with each of the machine-readable links being assigned in the linking service to a user account;
