% downloaded routine to allow tray switching on the
% ps-800II printer
% this was developed to fix a nasty bug in the hp emulation of the
% PS-800 II.  Ignoring the tray setting stuff, the emulation switching
% works fine on a ps-810
% to use, print this to the printer.  The printer will load
% this in and it will stay in the printer until the power is turned
% off.  If you are typing it in, use a texteditor that will allow
% you to embed the ESC character, or use the basic version to create
% a file.  It is used by sending an *E to start the HPLJ emulator
% you must then send an ESC &k3G to enable cr/lf's to work correctly
% with the HP emulation.  To Exit the emulation, you send an escape
% sequence.  The sequence is 27 7f 04.  The 04 by it's self will also
% work.  That forces an end of job.  Then to switch trays, you send
% the normal escape sequence of  ESC l1H and ESC l0H  Where ESC is
% chr$(27) or 1B.  This will cause the papertray to switch and then
% restart the emulation.  The only caveat is that ^C, ^T,^S,^Q and ^D
% cannot be included in the character stream.  This version does NOT
% put the machine in transparent i/o mode.  If you are using a PARALELL
% interface, it will be in transparent i/o mode.
% You MUST put a space in front of and after the trayswitch commands.
%
% The character ^D will cause the current emulation to be terminated
% on the spot.  The printer will kickout a page.  The ^C command will
% cause the job to terminate, but will NOT kick the page out.  This will
% let you embed POSTSCRIPT code and use postscript code to do what
% you want.  You can then restart the emulator.
