Does anyone use Bentley PLT drivers for KIP5000 plotter?

Have you tried setting something like:
/tray="Roll #1"

Have a look at the "Device Propertyy Page" tab on the Properties Dialog for your printer to see the tray/drawer names.

from printer.plt:

;   /tray
;           This value can be any valid tray name for that printer, e.g. Tray1, "Manual Feeder", etc.
;           Each printer manufacturer may have a different a list of tray names which
;           are valid for their particular printer.
;          
;           The easiest way to determine valid tray names is to open the Print Setup dialog
;           from MicroStation (or other application) pick the appropriate printer/plotter
;           and look in the Paper Size list box to see the valid names.
;          
;           Note: Some manufacturers have used tray names which contain characters outside
;           the normal ASCII printable range. To handle this case, the user can enter a "?"
;           in place of any character and MicroStation will match the actual name.
;          
;           If the tray name contains spaces or '/', it should be enclosed in "" or ''.
;           If the tray name contains " (double quote) as part of the name, the single quote
;           pair should be used.
;
;           The /tray qualifier is optional.  If omitted, the Windows default setting for the
;           named printer will be used.
