How to install a driver for the HP Deskjet 5550 on macOS 10.14? I want to print in color from an old HP Deskjet 5550 printer (17 years old and works without an issue, I heard). 


macOS offers Generic PCL Laser Printer for this device. It works (although it is not a laser printer), but only in black &amp; white. 
The old individual driver on the HP website doesn't work with macOS 10.14
Mac Printer Driver 5.1 (dated 20 September 2019 on HP website https://support.hp.com/us-en/drivers/selfservice/HP-Deskjet-5500-Printer-series/71895/model/71897, dated 2017 on the Apple website https://support.apple.com/kb/dl1888?locale=en_US) doesn't contain a driver for this model, as seen in /Library/Printers/PPDs/Contents/Resources and in the dialogue when adding a new printer.


What are my options?
You can use the Gutenprint drivers:
https://sourceforge.net/projects/gimp-print/files/

Click the "Download Latest Version" button.

Once you have downloaded the disk image and installed the drivers, make sure the printer is connected and powered up, then re-add your printer in System Preferences > Printer &amp; Scanners.  It should automatically select the Gutenprint driver.  Otherwise, manually select it.

Click "Add" and you are ready to print.
