Hi Robert_Steyn,
Welcome to the HP Forums, I hope you enjoy your experience!
I understand you are trying to setup the printer on Linux.
I will be happy to help you.
I have provided you with the HP LaserJet 1018 Printer Drivers that are available.
This is a link to the HP Linux Imaging and Printing page.
Hope this helps.
Thank you for posting on the HP Forums.
Have a nice day!
