Bob Thank you for putting this excellent process together - clearly everybody should do this every time they buy a different paper. Hmmmm, come to think of it there may be a business opportunity here! For those that can't or won't read I could charge a small (but nice) fee for advising them that we did all the tests and the paper passed but don't use it in Laser printers anyway because I just read the manual and it says not to! $25 please, ching ching. But I digress. Best wishes Tony MS MVP Printing/Imaging

Top posting is fine for email. For newsgroups, quoting *only* the portion to which you are replying, and replying directly below that portion makes the most sense. Q then A, not A then Q. Most of us are just tired of complaining to the "me, me, me" top-posters ("Top postings saves me valuable time which allows me to respond to many more queries."), and have given up. > Also, anyone following a thread will find top posting > considerably faster to read. Those new to a thread - whose server has not retained the entire thread - must search the quoted thread then go back up to the top for your reply. Faster? A time saver? I think not. Question, THEN answer. Just like normal conversation. 'Nuff said.

Yup, "inkjet"! My > wrapper doesn't say much but their website shows a slightly changed > wrapper and the website adds that it is I'm a little fussy about the feel of my paper too. I can't say Ihave had any luck at all with supermarket stuff. There are two that I like at the moment: 'Artwork' paper, stocked at Rymans and maybe elsewhere. Pink and white packaging. Nice feel, very smooth and good whiteness. I stocked up on the stuff a couple of months ago when Rymans were selling it at two reams for �5 but even at the regular �3.50ish a ream it's good value. 'Color Copy' paper, I've seen this at various places including Staples and several mail order places. It's on Amazon at http://tinyurl.com/6gonyq since the name alone is hardly likely to be unique. It's difficult to overstate just how nice this paper is. Nice weight (100gsm), very white, and so smooth you do a double take to make sure it really is paper and not some kind of plastic. I really have had people comment on the paper used when I hand over documents printed on that stuff. Alas, it's not cheap. Typically it's around �8 a ream from retail outlets and that's too expensive for an everyday paper in my book. -- Andrew Smallshaw andrews(a)sdf.lonestar.org
