Current Print:
When dviout is in the current mode, the mode can change to the mode set here only when Printing. (This becomes effective after the [Save] button is pressed.)
For example, you might want to employ different dpi when printing from when previewing (cf. Q_P6) or invoke Ghostscript to interpret PostScript \specials only when printing. By specifying a mode in Current Print, such a temporal switching of mode is possible.
