I did not personally buy this but it was given to me by someone conducting an office clearance and who had no use for the printer paper anymore. This is a Wh Smith own branded paper and it's of premium quality. It's intended for use for those more important documents, letters, invitations, reports etc.
The paper is A4 sized and comes in a 50 sheet pack and the sheets can be used in both inkjet and laser printers. This paper is slightly thicker than your average printer paper. An average thickness of printer paper is about 80gsm and this is 120gsm. It means this paper feels heavier and is bulkier. I would suggest if you have a multi page report or document that you consider the weight and thickness of all the sheets put together before using this paper as it can end up being quite bulky even with just a few sheets. The paper is plain white - bright and clean looking. It has a matt finish so it's not shiny but it still looks as though it has a 'finished' surface. When you look through this paper it's difficult to see through to the other side or to any pages underneath as you can do with thinner sheets.
This paper absorbs both black and colour inks well and dries very quickly after being processed through the printer. I very rarely experience any issues with the paper smudging or getting jammed. It seems to actually work through the printer more easily and more smoothly than thinner sheets.
This paper is high quality, there is no doubt, and it's definitely a good paper to have on hand for those documents which you feel you need a better quality paper. I've seen this online priced at £5.99 which is a very high price for printer paper so I'd recommend buying this only if you definitely know that you need a high quality printer paper.
This inkjet paper was an in between measure when I wanted to print some photos and didn't want to go to the expense of photo paper. The paper is 120gsm and each sheet immediately feels nice and thick when taken from the pack. "Gsm" means "grams per square metre" and is the measure of quality of paper, the higher the number, the better the quality. Normal printing paper used for general printing is between 80-100gsm, and 120-140 is usually the thickness of flyers, posters and so on. That means that this paper is ideal for any work like that, I have printed quite a few great quality advertisements for local events which stand up well to being pinned up in shop windows and notice-boards for a few weeks.
In terms of the paper itself, there is no doubt about which side is for printing on. The printing (coated) side is really bright white - I thought my usual paper was white until I put it against this, it's really whiter than white! It's also much smoother than standard paper, and has a slight sheen without actually being glossy/shiny. The other non-printing side is a slightly buff colour and noticeably less smooth, without being rough.
At £6.99 for 50 sheets, this paper is firmly in the premium market, but I only use it for specific printing jobs nowadays. The photo experiment wasn't a great success, as ultimately I felt they did need to be printed on gloss paper for the best effect. The colours did come out beautifully bright and defined, and the paper was dry on printing, but without the gloss finish, they didn't feel like true photographs to me somehow.
When printing on the paper I do put my printer to the "gloss paper" or high quality printing setting, just to get the best from the paper, and I have to say without exception, the results do come out looking as premium as the price.
