Understanding the IPP Gateway
InfoPrint Manager for Linux now includes an Internet Printing Protocol (IPP) Gateway. The IPP Gateway lets users anywhere in the network who have IPP client software installed to submit print jobs through InfoPrint Manager, even to printers that are not IPP-enabled. Users must follow the instructions provided with the IPP client to add a printer to their desktops. Use the InfoPrint Manager Web Management Interface (WMI) to enable the IPP Gateway.
- Important:
- You can start multiple IPP Gateway instances using both secured and unsecured protocols.
- To start the IPP Gateway services, ensure that the port you intend to use (the default port is 631) is not occupied by another service. On Linux systems, the cupsd service probably already runs on port 631, which is also used by CUPS DSS. Therefore, you need to start the IPP Gateway on a different port from 631. If you do not use CUPS DSS destinations on InfoPrint Manager for Linux, you can stop the cupsd service (but do not uninstall CUPS), and use the default port 631 for the IPP Gateway.
- Note:
- You can also use the startippgw and stopippgw utilities to start and stop an existing IPP Gateway. For information about these two daemon utilities, see the RICOH InfoPrint Manager: Reference.
- The Internet Printing Protocol (IPP) is an application protocol that uses the Hypertext Transfer Protocol (HTTP) to allow you to print your documents to any IPP-enabled printer whose web address (or Uniform Resource Identifier, URI) you know. You can use IPP to send print data over both LANs and the Internet, so users who are directly connected to your LAN, as well as those who work remotely, have access to the same printers.
An Internet Printing Protocol (IPP) Gateway printer is a printer that you create on a client workstation using IPP client software. Users submit print jobs to that printer, and they are sent to InfoPrint Manager through the InfoPrint Manager IPP Gateway. The IPP Gateway can then send the job on to any InfoPrint Manager printer, even those that are not IPP-enabled.
These are the IPP to InfoPrint Manager attribute mappings in the IPP Gateway:
| IPP attribute | InfoPrint Manager attribute |
|---|---|
| print-color-mode | color-bits-per-plane |
| media | default-medium |
| printer-resolution | default-printer-resolution |
| finishings | job-finishing |
| number-up | number-up |
| page-ranges | page-select |
| print-quality | print-quality |
| sides | sides |
| copies | copy-count |
| orientation-requested | content-orientation |
