hi
what version of android is it running as print options from browser werent supported in old versions if i remember.
it might be worth a go at downloading the printer app for the make of printer youre using and trying that,it may pick it up automatically when you hit print..worth a go.
also have a look for printershare in google playstore,we have to use that with our Launch X431 tablet but like you have to save as a pdf file first.
