I have soome problem with hp psc 1215 printer,all leds is on and the display in indicate 8.Please help me!?

if the display shows 8 that means that your printer has no big issue with it and and all hardware is ok. when there is any internal fault then your printer will show E in indicator not 8. If you give more specific information as to waht happens when you connect it to PC and give print command then I will be able to help you better. I have the same printer
