My computer doesn't send picture to be printed to my hp photosmart 8450. I have Windows Vista and it worked before. Now why does it show an error in the printer info and also, this printer is set as default. It seems to get hung up in the printer quece

Most HP drivers are available here: http://support.hp.com/us-en/drivers . Then search for your model. The direct link to the drivers for the Photosmart 8450 is http://support.hp.com/us-en/drivers/selfservice/hp-photosmart-8400-printer-series/402149/model/402151#Z7_3054ICK0K8UDA0AQC11TA930C7 . Select your OS version.

The Photosmart 8450 drivers should be found with the new hardware wizard in Windows 10. You'll need to connect the printer to the computer via a USB cable to start. (Make sure that the system is connected to the internet.)

I hope this helps.

The 8450 works with SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and will not work in devices not designed for them. SD cards will work in SD and SDHC devices, but SDHC cards will not work in SD devices.

try loading the drivers from HP
