Good cheap paper

The Avery Paper can be printed with good laser printers, both color and B / W. A pity, I find that no indication of the orientation of the paper is available: which way is up? Thus, the paper curls after printing, when placing it in the paper cassette of the laser printer "wrong direction". (A "wrong" does not exist actually, since the paper from both sides is white - but if it is placed in the correct orientation in the laser printer, it does not roll together - I do not know if that's in ink printers also so , laser printers that's just so). This can be a quite a mess when printing times many pages, and all these can be rolled up. Enjoy Order I say only ...
That with the 80 g must also believe - or remeasure. On the packaging, I have found no indication of the severity of the paper. In addition, I found the shipping container a little exaggerated - you should actually the same order multiple packet ... but still "works" the product so far properly.
