CUPS test page prints but nothing else can print

[Chris Green <cl@isbd.net>]

I have just [re]installed an HP Laserjet Pro M15w printer on my T470
laptop which runs Debian 12.

The CUPS test page prints succesfully but nothing else seems able to
print.  The CUPS Print Status window shows the job for a few seconds
but then it flashes the red cross indicating an error and the job
disappears.

I have discovered that using lpr from the command line works (just
plain text in other words).

This printer used to work fine, all I have changed is the WiFi
connection because I changed the router.

The driver being used is drvless.ppd.

What might be wrong?
