Are you annoyed because you are unable to register your printer with Google Cloud Print?
Do not be worried. It is not a big deal because Google Cloud Print is a Google service that allows users to print from any Cloud Print-aware application on any computer in the network cloud to to the cloud print services.
It is not desirable, and sometimes difficult, to reproduce the complex printing architectures of conventional PC operating systems on these modern devices. Nobody in the printing community – consumers, developers, and printer manufacturers – wants the “driver mess” to get any worse.
It is done with the help of a cloud printing service. Apps no longer depend on the operating system (and drivers) on the local machine to print. GCP is then in charge of sending the print job to the appropriate printer, with the user’s choices and informing the app of the job status.
Let me share all the details with you that I have learned after conducting extensive research on this topic. Stay tuned and read the entire article all the way through. Today, you might learn something new, so let us get started.
Register printer with google cloud printer.
It will aid printer and printing software developers in integrating their solutions with Google Cloud Print services so that their printers can obtain jobs from the Google cloud. A printer must be able to manage the three steps outlined in this article to integrate with Google Cloud Print:
- It registers the Google Account for the user.
- Sync its features and status to the cloud.
- Handle any cloud-based print jobs that have been queued.
1-Register the printer.
Before a customer can access the printer, it must be registered with GCP. The printer provides semantic data during this process. This phase can be performed by a software program that “proxies” or “connects” the printer or the firmware can perform it on the printer.
There are three general steps for registering:
- The printer (or connector software) receives a registration token after making an unauthenticated register call with semantic information about the printer. A user action is required to start this process (either by manual interaction or by the Privet Local Discovery protocol).
- The user claims the printer by submitting an authenticated request to a particular URL with the registration token.
- The printer sends a non-authenticated request to complete the registration procedure and then receives GCP communication credentials.
In the connector application case, the application must use the robot account credentials from phase 3 to authenticate calls to the /register interface to register any other printers it may serve.
What is Robot Account, and Why must I use it?
A robot account is a Google account that is controlled by a human account. The names of the robot and human accounts are not exchanged, let alone their credentials. The primary goal of a robot account is to limit user data access and keep the identities of the user and the printer separate. This procedure has several intriguing advantages:
- If the robot account credentials are compromised, only the robot’s printers are revealed, not the user’s other printers.
- And if the user has registered other cloud-ready printers or even other instances of the connector, the connector can only see the printers it has registered.
- To more specifically evaluate when a printer is online, GCP may differentiate between various connector software instances. If GCP needs to know if a printer is online, it checks the GTalk (XMPP) Status of the identity associated with the printer.
- Suppose that identity is shared with another instance of the connector program. In that case, a false positive will occur if the other connector instance had an active XMPP link to the GTalk service.
- Quotas for API requests are more uniformly distributed. If all a user’s printers represented themselves as the user when making API requests, the API requests would be charged to that one identity, resulting in unfavorable rate-limiting for users with many printers.
- The robot account’s rights can be restricted to those required for its function.
When the printer first comes online, it can connect to the Cloud Print service and match the printer’s status and capabilities with the cloud listing. It eliminates the client’s need to keep track of what has been registered, leaving only the Auth token issued when the user authenticated.
The printer ID is the key given by Google Cloud Print for retrieving and managing jobs for a particular printer in the cloud. For requesting the inclusion in the response object of printing fields, such as queued Jobs Count, an extra field parameter is passed on to the interface /list.
To retrieve a printer’s features, you must use the /printer interface.
3-Handling Print Jobs
A persistent XMPP link is used to deliver notifications from the Google Cloud Print service to printers. The printer should initiate this link with the Google Talk XMPP servers. The OAuth2 access token you got during registration will also function for Google Talk authentication. For production purposes or printers with at-device authentication, it is possible to miss the notification stage.
As jobs are completed or errors are found, the printer may use the /control interface to change job status and transmit it to the user. A job ID (required) and a semantic status, error code, and error message are passed as parameters to the /control request. The/fetch protocol will return only jobs in the QUEUED state.
Google Cloud Print (GCP) is a Google cloud-based printing service for printing on any device. Users bring their own mobile devices (BYOD) into work increasingly and need a solution for printing. Google Cloud Print offers a printing tool that runs Android or iOS from all mobile phones or tablets.
To be available to users to print, printers must be published on Google Cloud Print. Only a click is needed to publish a printer once the Google Cloud Print is turned on. It is the easiest way to register your printers with Google Cloud printers. It is all the information I have collected.
