You mean printing everything on the screen? Attributes are not printed
by default, but you can print them by giving extra arguments to the
print.igraph() function. You can also make printing them the default:

igraph.par("print.edge.attributes", TRUE)
igraph.par("print.graph.attributes", TRUE)
igraph.par("print.vertex.attributes", TRUE)

Best,
Gabor
