Re: hp deskjet 3512 not printing

Hi,

That appears to be one of two issues, the documents entering the print queue and not being pushed out to the printer, or the spool system in the computer isn't working correctly.

Try this utility first: HP Print and Scan Doctor. Run it for fixt printing. It will try to detect and correct any issues on the computer to do with printing.

There's also this document: Print Jobs are Stuck in the Print Queue.

Try out both, and let me know how it goes for you.
