% config.tray1
% Configuration and header file for dvips. Load with: dvips -P tray1
%
% Selects paper from "tray 1"
%   - often this is the manual feeder / upper tray / multipurpose tray.
% This should work with these HP LaserJet printers:
%   4/4M Plus PS 300 + 600
%   4V/4MV PostScript
%   5/5M PostScript, 5P/5MP PostScript
%   5Si/5Si MX PS, 5Si Mopier PS
% This is very unlikely to work with these HP LaserJet printers because they
% select trays via media type and not media position:
%   4Si/4SiMX PS 300dpi + 600dpi
%   4/4M PS 600 dpi
% Tested with:
%   gs 5.10, ...
% Will be silently ignored by a PS level 1 PostScript interpreter,
% or any other which doesn't know /MediaPosition.
%
% This file is built so it can be used both as the header file for
% PostScript and as the configuration file for dvips.
% (Note that dvips ignores any lines beginning with a space or a "%".)
