PWG 5100.2 is missing a keyword value for roll-fed printers. While technically most roll-fed printers produce face-up output (and thus could use the value 'face-up'), this also has the unfortunate connotation that the stacking order is reversed since most printers producing face-up output *do* stack the output in reverse order.
The JPS3 printer-output-tray attribute and corresponding Printer MIB prtOutput properties do provide the correct stacking order, direction (up/down), and type of each output bin/tray, however printer-output-tray is still not widely supported and would seem to be overkill for just describing that a printer's output is not stacked.
Does anyone object to adding a new value of 'roll' for the "output-bin" attribute?
