A machine with Fedora 23 installed will act as a print server for both Linux and Windows clients.
What is really nice is that using ipp, CUPS can now share printers over the network to Windows clients without messing with Samba configuration!
At first, I naively thought that simply installing cups and xsane would be suffcient:
sudo dnf install cups xsane
However these packages and their dependencies are not sufficient for getting the MG2490 to print or scan.
Initially I also tried installing the package cnijfilter-mg2400-series.rpm.
Referring to /var/log/dnf.log Here are all the packages I installed on Fedora 23 server for the Canon Pixma MG2490:
cups
gutenprint
gutenprint-libs
gutenprint-foomatic
gutenprint-cups
foomatic
foomatic-db
system-config-printer (optional, but recommended)
system-config-printer (optional, but recommended)
sane
sane-backends-drivers-scanners
sane-backends
sane-backends-drivers-scanners
sane-backends
xsane (optional, but recommended)
Once everything is installed, start the cups systemd service:
systemctl start cups
Make sure the MG2490 is connected by USB cable to your CUPS print server and then run system-config-printer as root. Select "Add" and choose printer and your MG2490 should appear in a list. Choose the "USB MG2490" entry. The gutenprint-foomatic package includes a postscript PPD file for the Canon MG2400 series, so your printer should appear in the list under Canon printers
Since
you will be sharing this printer on the network, in the printer
properties make sure it is shared for all users. One of the dialog boxes
will also offer to set up rules for CUPS and IPP in firewalld (how
convenient!).
If you don't use system-config-printer, however, you will have to add several rules to firewalld manually using the gui firewall-config or on the command line with firewall-cmd.
In your default zone, open up port 631/tcp (for CUPS remote administration http interface) and also allow ipp-client traffic.There might be other settings required, but these are the ones that occur off the top of my head (I just used system-config-printer because I'm lazy).
Now from the server machine, open a browser and navigate to http://localhost:631, login to Printer Administration with root:password
for your server, and print a test page. You can also print a test page from system-config-printer.
Other Linux clients can find the CUPS server if you enter it's IP address in the system-config-printer "Network Printer -> Find Network Printer" dialog box.
To add the Canon MG2490 for Windows clients, click on Control Panel -> Add New Printer, and select Network Printer.
In the address bar, enter the IPP address of your printer listed in CUPS. You can find this address in the CUPS web admin page on port 631 or through system-config-printer. In my case, the IPP address is:
ipp://192.168.30.6:631/
But in the "Add Network Printer" dialog box on Windows clients, change this to http:
http://192.168.30.6:631/
http://192.168.30.6:631/
Note that the Windows client must have windows drivers for the MG2490 installed. Windows users will be prompted to select the printer driver. They should select the driver named "MG 2400 series". In the case of Windows 10, however, it will automatically detect the printer and install all drivers for the printer and scanner automatically! Once the printer is set up, have the Windows user print a test page. In my experience the initial test page took > 1 minute to print, but subsequent print jobs from Windows clients were processed much more quickly (< 30 sec).
It is such a relief to be able to set up a Linux print server for Windows clients without messing with Samba shares. Thank you, Linux + IPP!
