Tried to print a job with my Fuji-Xerox laser printer, it didn't want to work at all, the dialog box in the print window either said it was offline or waiting to finish an existing job. Neither of those statements were true.
F-X are known to be a tad slack with certain printer drivers, I certainly hadn't downloaded any for macOS 10.13, but I had for 10.12. They'd been slow in getting drivers for it under El Capitan but this time there's a High Sierra version. Installed & works fine.
