Re: [cups] Cups shared printers not showing in Windows 10 or 11

Also might not be finding it as the HLL2300D queue is in a turned-off, stopped state and paused.

Hi Todd,

Win10 1809 includes the IPP inbox class driver which added support for Mopria certified network printers (and with Win10 21H2 also over USB) and it discovers the network printer over mDNS (aka Bonjour).

Try 'avahi-browse --all -r' and see if the missing HLL2300D print queues is being advertised over mDNS. With the version of CUPS you are using, you should see a mopria-certified attribute in the mDNS advertisement.

If it can't find the print queue, you can manually add a print queue that use the IPP inbox class driver by running the following from the command line:

rundll32 printui.dll,PrintUIEntry /ip

then press the next button and enter something like the following for the IPP address:

   ipp://xxx.xxx.xxx.xxx/printers/HLL2300D

Or from an administrator poweshell command-line issue:

  Add-Printer -IppURL ipp://xxx.xxx.xxx.xxx/printers/HLL2300D



Cheers,
Doug

Hi All,

Fedora 38
cups-2.4.7-1.fc38.x86_64
cups-lpd-2.4.7-1.fc38.x86_64

My old printer broke, so I had to replace it.

I removed the old printer from cups and added the new printer.  I set the new printer to network share (and indeed does share over LPD).

/etc/printcap:
# This file was automatically generated by cupsd(8) from the # /etc/cups/printers.conf file.  All changes to this file # will be lost.
HLL2300D|HLL2300D:rm=server.acme.local:rp=HLL2300D:
Cups-PDF|Cups-PDF:rm=server.acme.local:rp=Cups-PDF:

"Cups-PDF" shows in the Windows 10 "add printer" dialog, but my new HLL2300D does not.

I have cups-lpd installed, so I just did a manual create an lpr port on Windows 10 and my new printer works fine from Windows 10. If it means anything, all my Samba shared do show.

But, why can Windows 10's "Add Printer" dialog not find it?

The HLL2300D in  /etc/cups/printers.conf
