Question: can't install HP PSC 1310 setup software Driver not digitally signed or appropriately.? 

Answer: HP PSC printers have so much equipment (scan, fax, mem card), that I have had to reinstall often.\n\n1) Try going to the HP website try both the full and basic drivers.  (Install and then use uninstall each time)\n\n2) make sure you have permission on your computer (I ran into this once)\n3) if it prompts you that you can install, but with a warning, go ahead and install, but make sure the software is from the main hp website. You may need to download and update your computers OS.
