You may have to re-add your printer to the print queue in System Preferences for the system to read the machine again. How does the printer connect to your MacBook Pro? Is it a wifi printer or USB system? I've also got this helpful article on the basics for re-adding the printer and joining the print queue, let me know if this helps out with this issue.
If not, describe the connection type of the printer and whether or not it's viewable in System Preferences -> Print & Scan as an added printer or not ^_^
