You can select trays from the printing properties of the 2x universal printer.
If you want to open the local printer properties each time a print job goes through EMF or BMP mode run the following from command line on the client.
Code:
reg add HKEY_LOCAL_MACHINE\SOFTWARE\2X\AppServe rClient /v PrintUseProperties /t REG_DWORD /d 2
Like this you have the options of your local printer opened before the printer job goes through.
Remove this key once you do not want to see the options pop up any longer.
Another solution is to print through your acrobat reader if you select pdf mode and enable view before printing.
Hope this helps
Thanks
