第 6 章 Driverless USB printing and scanning

Procedure

1. Install the ipp-usb package:

   # dnf install ipp-usb

   注意

   The ipp-usb package is installed by default with CUPS and sane-airscane packages.

2. Check if device has printing functionality:

   1. Verify that the device is recognized by ipp-usb:

      # sudo ipp-usb check

   2. Check if the device is identified by CUPS among existing destinations. The service name created by ipp-usb has the suffix _USB.

      $ lpstat -e
      Canon_MF440_Series_USB

      The service name created by ipp-usb has the _USB suffix. For example, here Canon_MF440_Series_USB represents IPP-over-USB device called Canon I-Sensys MF433

      重要

      If the Canon_MF440_Series_USB is displayed in the output of the lpstat -e command, but not in your application, report the issue to the application.

   3. Check device capabilities:

      # ipptool -tv ipp://localhost:60000/ipp/print get-printer-attributes.test
      
      # lpoptions -p Canon_MF440_Series_USB -l

      The ipptool command returns all IPP attributes which the device supports. If your printing option is present in IPP response, but not in lpoptions output, then it is a CUPS issue because the common PPD options are generated from some of the attributes. The lpoptions utility returns available PPD options.

3. Check if the device has scanning capabilities:

   1. Check if the sane-airscan backend recognizes your device:

      # scanimage -L
      
      device `airscan:e0:HP LaserJet MFP M130fw' is a eSCL HP LaserJet MFP M130fw ip=127.0.0.1
      Here, the HP LaserJet MFP M130fw device here is used for illustration, it does not show its real IPP-over-USB compatibility or its real options shared via AirScan from ipp-usb.

   2. Check the device capabilities:

      # scanimage --help -d 'airscan:e0:HP LaserJet MFP M130fw (E700D6)'
