I have a little HP Laserjet P1102w, decent little home printer, never any issues with it. I've had it connected to my Windows computer with a usb cable for about 5 years or so. Works perfectly. But when I connect it to my 2017 iMac with the same cable and install the basic PCL driver, this occurs when trying to print: The iMac sends the print job, I can see it in the queue, no errors. The print job finishes and leaves the queue, but the printer does nothing. No error lights or messages anywhere on the computer or printer. Verified again that it works on the Windows machine with the same cable. The USB ports on my iMac are fine, I use them regularly with thumb drives and camera memory card adapters. No other printer driver is available on the HP support site for that model. And of course the usual suggestions on "printer issues" support pages don't apply. They all seem to refer to error messages or driver installation problems. The cable is at least 5 years old but works on the Windows machine. Should that cable be a suspect? I don't have another cable at the moment but could certainly go get a newer one. It's such a simple setup plugged in directly, it should work as is.
