Note

If you have a page size-independent HP-GL/2 image, there is no need

 

to set plot size, otherwise it is good practice to set plot size.

 

 

The commands that allow you to set up a PCL Picture Frame and enter/exit HP-GL/2 mode are discussed in detail in the rest of this chapter. By reading the following command descriptions, you can see how changing command parameters can affect your printed output.

Horizontal Picture Frame Size

This PCL command specifies the horizontal dimension of the window to be used for printing an HP-GL/2 plot.

EC * c # X

 

 

# =Horizontal size in decipoints (1/720th inch)

 

Default

=

width of the current logical page

 

Range

=

0 - 32767 (valid to 4 decimal places)

 

 

Note

The horizontal dimension specified is parallel to the PCL X-axis

 

when the print direction is set to 0 degrees (the default).

 

 

 

 

Using this command defaults the location of P1 to the lower left corner of the picture frame, and P2 to the upper right corner of the picture frame. It also resets the soft-clip window to the PCL Picture Frame boundaries, clears the polygon buffer, and updates the HP-GL/2 pen position to the lower-left corner of the picture frame (P1), as viewed from the current orientation.

If no horizontal picture frame size command is used, the printer defaults the picture frame size to the logical page width. A parameter value of 0 or the PCL reset, UEL, page length, paper size, or orientation commands default the horizontal picture frame size.

If an HP-GL/2 plot size is specified, the horizontal picture frame size is used to determine the horizontal scaling factor used for scaling the image to fit in the picture frame.
