waiting for printer to become available error message
I haven't been able to print - using my HP Deskjet 1510 printer for the past weeks ..... due to the current driver, etc, problems.
AFTER FOLLOWING SIMPLE INSTRUCTIONS FROM THIS BLOG SPOT LINK - ENSENSO - MY PRINTER NOW PRINTS & SCANS PERFECTLY AGAIN. I hope that this link brings success for you as well .........
