6.1.3 Graphics Dump Data

The fDump dialog box contains controls which specify how the printer
processes bytes of graphics data, whether the printer supports color at the
specified resolution. You display the fDump dialog box by double-clicking
the fDump entry in the Resolution Bitwords list box. The fDump dialog box
is shown in the following illustration:

bitmap:  fdump

The following list describes the significance of the controls in the fDump
dialog box:

Control             Meaning
---------------------------------------------------------------------------

RES_DM_GDI          Specifies that each byte of bitmapped data corresponds
                    to 8 consecutive horizontal pels of bitmapped data.
                    This is the same format used by the Windows graphics
                    device interface (GDI).

RES_DM_LEFT_BOUND   Specifies that the Universal Printer Driver should
                    attempt to minimize the amount of raster data sent to
                    the printer in each band. The Universal Printer Driver
                    will do this by substituting cursor-movement commands
                    in place of white space raster data to the left of the
                    bounding rectangle that contains all the raster data in
                    the band that can be printed. If this bit is not set,
                    the Universal Printer Driver will control horizontal
                    positioning of raster data by moving to the leftmost
                    printing position on the page and padding the null
                    raster data.

RES_DM_COLOR        Specifies that the printer supports color output at the
                    specified resolution.


Diconix 150 Plus

For the Diconix 150 Plus printer, each byte of bitmapped data corresponds
to a vertical column (not a horizontal row) of 8 adjacent pels; therefore,
the RES_DM_GDI box is not checked. The optimization described for the
RES_DM_LEFT_BOUND bit are preferred, so that bit is checked. This printer
does not support color output at any resolution, so the RES_DM_COLOR box is
not checked.


HP LaserJet IIP

For the HP LaserJet IIP printer, each byte of data corresponds to 8
consecutive horizontal pels, so the RES_DM_GDI box is checked. However,
this printer does not support color output at any resolution, so the
RES_DM_COLOR box is not checked.
