In the control panel it says this is the default printer and is ready and has a green tick. but it just won’t print. if i turn computer off then on again then it will print whatever is in the print queue but nothing else.
I am running Vista. I have tried Windows help & support and HP troubleshooting too.
I have attempted to reinstall the printer.

ok i have a hp deskjet d2330 printer, and the thing is, it use to print and was fine. i have reinstalled it numersous times but it keeps saying that the printer is not connected to the computer. after a while we went as far as buying a new printer and cords altogether but now its doing the same thing again. help???…….

I just bought a new Hp deskjet F4280 and im trying to get it set up i followed the instructions but it won’t print an alignment page!! some people said go to the settings and click “align cartridges” or something but thats not their EITHER! i need help ASAP please! I tried to scan something without printing the alignment page but all it gave me was a blank white page!!

The first time it didn’t list Vista as a operating system it can be installed on,then I tried again and it says the following reasons were preventing intalation and listed like 4 diff things,is there some update that it didn’t pick up or something I can do to get it on here?I don’t wanna buy another printer this is so irritating….thanks for any help
