When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

quality achieved is comparable to xxx dpi true resolution
There is a difference between "class resolution" and "true resolution", nicely described here:
----
Resolution. True resolution, measured in dpi horizontally and vertically, is the routine measure of printer output quality.
The 600-by-600-dpi resolution of most color lasers is more than adequate for high-quality text and color graphics. You can increase resolution to 1,200 by 1,200 dpi or higher by adding RAM to a printer with a fast processor.
Image resolution software, such as HP’s ImageREt 2400 and other proprietary technology bundled with a printer, can further enhance both color and black-and-white images, giving the impression of higher resolutions. Some manufacturers fudge the question of resolution by listing their 600-by-600-dpi printers as having “1,200- or 2,400-dpi class resolution.”

For instance, a 1200 dpi class resolution printer might in fact have a true resolution of 600x1200 dpi, as described for the OKIPAGE here http://www.dumaco.co.uk/oki/mono/okipage_14_series.htm

Dots per inch (DPI) is a measure of printing resolution, in particular the number of individual dots of ink a printer or toner can produce within a linear one ...

DPI (dots per inch) is a measure of the resolution of a printer. It properly refers to the dots of ink or toner used by an imagesetter, laser printer, or other printing device to print your text and graphics. In general, the more dots, the better and sharper the image. DPI is printer resolution.

resolution in dots per inch
'True' 600x600 dpi indicates that all the ink dots come from the source image to be printed, are not interpolated by the printer/SW.

not true 600/1200 dpi
| agree |
Klaus Herrmann
: Yes. I read this as not having a true 600 dpi resolution. E.g a 300 dpi Laserjet 3 with RET. I didn't think 300 dpi printers still exist (obviously, we're talking about laser printers.)

dpi class
dots per square inch
| disagree |

: If dpi stood for dots per SQUARE inch, the abbreviation would be dpsi. A so-called 600 dpi printer has 360,000 dots per square inch. See http://www.webopedia.com/TERM/d/dpi.html and http://en.wikipedia.org/wiki/Dpi (mind the word "linear" in the latter)
