The new text (ini the current draft) clarifies that "The hrDeviceStatus column
shows the hrDeviceStatus which is typically appropriate when such an error
condition exists." In other words, there isn't a strict algorithmic
translation between errorState bits and deviceStatus. deviceStatus should be
set based on the operational status of the printer. errorState bits should be
set based on any detected errors. If the noPaper condition is set but the
printer is still able to run, this would be highly unusual, but OK. The
deviceStatus column just suggests the most likely condition.
Adding warning or down to all rows is less useful and actually provides less
flexibility than implementors might need.
