Chapter 5. Determining whether a printer supports driverless printing
CUPS supports driverless printing, which means that you can print without providing any hardware-specific software for the printer model. For this, the printer must inform the client about its capabilities and use one of the following standards:
- AirPrint™
- IPP Everywhere™
- Mopria®
- Wi-Fi Direct Print Services
You can use the ipptool utility to find out whether a printer supports driverless printing.
Prerequisites
- The printer or remote print server supports the Internet Printing Protocol (IPP).
- The host can connect to the IPP port of the printer or remote print server. The default IPP port is 631.
Procedure
Query the
ipp-versions-supportedanddocument-format-supportedattributes, and ensure thatget-printer-attributestest passes:For a remote printer, enter:
# ipptool -tv ipp://<ip_address_or_hostname>:631/ipp/print get-printer-attributes.test | grep -E "ipp-versions-supported|document-format-supported|get-printer-attributes" Get printer attributes using get-printer-attributes [PASS] ipp-versions-supported (1setOf keyword) = ... document-format-supported (1setOf mimeMediaType) = ...For a queue on a remote print server, enter:
# ipptool -tv ipp://<ip_address_or_hostname>:631/printers/<queue_name> get-printer-attributes.test | grep -E "ipp-versions-supported|document-format-supported|get-printer-attributes" Get printer attributes using get-printer-attributes [PASS] ipp-versions-supported (1setOf keyword) = ... document-format-supported (1setOf mimeMediaType) = ...
To ensure that driverless printing works, verify in the output:
-
The
get-printer-attributestest returnsPASS. - The IPP version that the printer supports is 2.0 or higher.
The list of formats contains one of the following:
-
application/pdf -
image/urf -
image/pwg-raster
-
-
For color printers, the output contains one of the mentioned formats and, additionally,
image/jpeg.
