Testing connectivity to printers

Debugging printer connections from the client

When clients fail to connect to the printer they will display the following error message

or an error message 'Query Fail' or 'Print failure, client error'

To resolve errors like this it's useful to confirm client (Chromebook) connectivity to the printer.

The Coreza Print application contains a basic set of connectivity tests that can be run.

Open the Coreza Print application
On the printers tab, use the three-dotted button to reveal the connection test button
Click on 'Connection test' to run a connection test.

Error Message	Cause	Remedy
ERR_NAME_NOT_RESOLVED	The printer is completely offline or not reachable.	Check the printer is turned on and that a client device on the same network can ping the printer.
Port closed	The printer is reachable but a service (port) is unavailable. Printers will need at least IPP, IPPS or port 9100 services to be enabled to allow printing.	Log in to the administration console of the printer (accessed via http://<ADDRESS of PRINTER>) and check that: The printer supports IPP printing That IPP or IPPS is enabled If IPPs is enabled, disable any option that refers to 'force IPPs' or 'upgrade to IPPs'. Conversely, check 'allow insecure IPP' for the purposes of this test. That RAW / PORT9100 / DIPRINT is enabled on the printer
Printer status: Failed to fetch	There was a problem with the IPP communication, your printer may require a special connection mode.	Please email support@directprint.io with your printer make and model and we will advise further.
