I have messed something up while trying to share printer over network. I am not able to access it from any remote computer. I guess that the problem is with router I have on my home network. How should I configure router to allow printing from other computers? Thank you in advance.
Router is usually not the problem for printing. Many routers have by default opened port needed for printing. If it is not a case check router settings and forwarded ports. Also check if you have shared printer correctly and if you have installed network printer on other machines instead local one.
