I am on a public computer at my university and I need to print some notes (it is the only way i am allowed to do it for free). The interface is limited to basically firefox and it uses gv to open pdf files, I have no access to console or any other program via a menu etc. So when printing part of the top of the page is missing i.e. it is off the margin. I tried some of the options in the menu but they are very limited. It gives me the option to use the lpr command but I could not find how to fix this using it. I did choose A4 format but no difference. Help?
