Old PSC 950 working perfect with windows 7 until Windows automatically updated me to Windows 10. Now printer won't print a full page, error message regarding printer drivers, but scanner, fax and copier work fine. This printer is awesome and I'd like to keep it. I'd buy a new one but reviews on new printers have so many complaints about paper jams and poor installation and support.
After you install 7-Zip, right click on the printer driver file you downloaded, and select 7-Zip from the list of items on the menu.
Have 7-Zip Extract to: and let it extract the driver file into its folder name.
Then use the add printer wizard in the windows control panel.
When you get to the part where you are asked to install a driver for your printer, click on Have Disk and browse to the printer driver file 7-Zip created\prnhp001, and select the HP PSC 950 printer from the list, and see if the driver installs that way.
