Most of the text is OK, but please replace the paragraph (in section "Debian CUPS as an IPP Everywhere Client")
----------CUPS has a PPD generator for IPP Everywhere printers and a PPD will automatically be created in /etc/cups/ppd. The PPD is based on the capabilities of the printer polled over IPP so these and user-settable options will be shown in the print dialogs of applications and by command line tools. Without a PPD printing is done with everything on default; A4, one-sided, normal quality etc.

----------Note that when an IPP printer is discovered that always a PPD is generated, if there is an IPP printer with a known PDL (PWG Raster, PDF, PostScript, PCL) which does not completely fulfill the IPP Everywhere standard, also a PPD is generated but capabilities about which the printer does not provide information are filled in with defaults. If there is no way to generate a PPD (printer has unknown PDL or does not tell its PDLs), no queue is generated. So no queues without PDLs are generated for network printers.
cups-browsed also generates local queues for remote CUPS printers but never uses IPP Everywhere for it, but the fact that one can download the remote queue's PPD of a CUPS server.
Thanks. Till
