Scott,


In my opinion subjective attributes are not very useful. Print quality, 
 for example, is so subjective that 'high', 'medium', and 'low' just 
 don't cut it. Also, a user's perception of 'high' or 'low' print 
 quality evolves with the state of the art. Why not specify objective 
 attributes like resolution, process (e.g. ink-jet, laser, etc.), color 
 capability (e.g. monchrome, full process color, etc.)? Cost is also 
 highly subjective (one man gathers what another man spills). Marketers 
 are constantly manipulating cost-per-page estimates in order to 
 position a product more competitively (some include only toner, some 
 include other supplies as well). Costs also evolve very rapidly over 
 time. Who would make these subjective judgements?


My two cents per page :)

Keith Carter and I met and we want to run the following issues by the
team:


We want to have a Location attribute. We propose that this should be a "
a free form string that can contain any site specific location information." 
How should filtered searches work on values of this attribute?


We want to introduce a new attribute callled Print Quality. "This indicates
a somewhat subjective evaluation of the overall printing quality: "high",
"medium", or "low"  "  ISSUE:  Does this subsume the need for Resolution
and Speed?


We want to introduce a new attribute called Cost.  "This indicates a
somewhat subjective evaluation of the overall cost of printing at this
printer: "high", "medium", or "low".   "  ISSUE: Is this a good thing or not?


We propose a Fonts Supported attribute which is the same as the
fonts-supported attribute in the Printer object.  ISSUE: Do you agree that
this should be in the directory entry.  Some studies have shown that
users want to search for printers based on this attribute.


If we keep Maximum Speed should it be moved to "high, med low"??


We propose a P1284 Device ID not a plug and play Id -- the plug and play
id can be created from this.  ISSUE: Does this subsume the need for
Make, Model, and Type??
