Understanding the IPP Gateway
InfoPrint Manager for AIX provides 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.
- 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 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 |
| orientation-requested | content-orientation |
| copies | copy-count |
| media | default-medium |
| printer-resolution | default-printer-resolution |
| finishings | job-finishing |
| job-hold-until | job-hold |
| job-priority | job-priority |
| number-up | number-up |
| output-bin | output-bin |
| page-ranges | page-select |
| print-quality | print-quality |
| sides | sides |
The IPP Gateway transparently converts incoming PWG Raster (image/pwg-raster) data to PDF before submitting jobs to InfoPrint Manager.
The following color spaces are supported for PWG Raster input:
| Color Space | Bits/Pixel | Description |
|---|---|---|
| DeviceGray | 1, 8, 16 | Monochrome/Grayscale |
| sGray | 8, 16 | sRGB Grayscale |
| DeviceRGB | 24, 48 | Device RGB |
| sRGB | 24, 48 | Standard RGB (most common) |
| AdobeRGB | 24, 48 | Adobe RGB wide gamut |
| CMYK | 32, 64 | Process color |
