Scaling Mode
Select the mode for determining the document size from the obtained active
coordinates area. Use active coordinates area to determine whether the paper
orientation will be portrait or landscape.
If it is an Active Coordinates Area
To obtain the document size, subtract the area specified in paper margins from the
active coordinates area obtained in the area determination mode.
If it is a Paper Size
Set the document size from the obtained active coordinates area and the origin point
setting. The document size can be selected from six sizes of A series paper (A0, A1,
A2, A3, A4, or A5).
How to Determine Document Size
The document size is determined by comparing with the hard clip area of each paper
size based on the active coordinates area obtained in the scaling mode, paper margin,
and area determination mode.
If the Scaling Mode is a Paper Size
1) Obtain the coordinate area to be active from the HP-GL data entered, in
accordance with the area determination mode.
2) As a margin, add the larger value of either the font size specified in the page, the
default size or one half the specified pen width, to the active coordinates area
obtained in step 1.
3) Subtract the value set in paper margins from the active coordinates area obtained
in step 2.
4) The minimum size that includes the active coordinates area obtained in step 3 will
be the document size.
If the Scaling Mode is the ACA
1) Obtain the coordinate area to be active from the HP-GL data entered, in accord
with the area determination mode.
2) As a margin, add the larger value of either the font size specified in the page, the
default size or one half the specified pen width, to the active coordinates area
obtained in step 1.
3) Subtract the value set in paper margins from the active coordinates area obtained
in step 2.
