2.3. Printable Area
For the purpose of printing, a sheet of paper is divided into two regions: the printable area and the non-printable area.
These areas are defined as follows.
The printable area is the region within which the printing position can be set, and is the portion which is surrounded by the
left margin position, the right margin position, the top margin position, and the bottom margin position.
The non-printable area is the region in which the printing position cannot be set, except for the right margin position, and is
the region on the paper outside the printable area.
The margins, which determine the printable area, are defined as follows.
The left margin determines the non-printable strip appended to the left side of the printable area. The left margin position,
which defines the margin boundary, is set upon the X axis. Moreover, the left margin position is considered as being
included in the printable area.
The right margin determines the non-printable strip appended to the right side of the printable area. The right margin
position, which defines the margin boundary, is set upon the X axis. Moreover, the right margin position is considered as
being included in the non-printable area. However, it is possible to set the printing position to the right margin position.
The top margin determines the non-printable strip appended to the upper side of the printable area. The top margin position,
which defines the margin boundary, is set upon the Y axis. Moreover, the top margin position is considered as being
included in the printable area.
The bottom margin determines the non-printable strip appended to the lower side of the printable area. The bottom margin
position, which defines the margin boundary, is set upon the Y axis. Moreover, the bottom margin position is considered as
being included in the printable area.
The page management X-Y discrete coordinate system (hereinafter abbreviated as the page management coordinate system)
which is used as the reference for setting the position of each of these margins, is the same as the position management
coordinate system, except for the definition of the origin.
The position management coordinate system is the coordinate system for management of the printable area which is set
within the page management coordinate system.
The position management coordinate system is set for each page separately.
The origin of the page management coordinate system is defined as follows.
The origin upon the X axis is set to the minimum printing position. The minimum printing position is the farthest leftward
printing position that can physically be set upon the paper. The minimum printing position depends upon the horizontal
position of the paper when it is inserted.
As for the origin upon the Y axis, for the first page directly after paper insertion, the upper edge of the paper is defined as the
origin. For the second and subsequent pages, a position advanced by the page length from the origin on the page
management coordinate system for the previous page is defined as the origin for the current page. Since in the case of
single sheet paper only one page at a time can be inserted, the upper edge of the paper is always taken as the origin.
Here, page and page length are defined as follows.
A page means a unit region in the Y direction which includes within it a single printable area if the paper which is inserted is
single sheet paper, only one page can be established upon each sheet. If the paper which is inserted is continuous paper, a
plurality of pages can be established upon it.
The page length is the length in the Y direction of the page. If the paper which is inserted is single sheet paper, the length
of the printing region in the Y direction from the top margin position to just before the bottom margin position is taken as the
page length. If the paper which is inserted is continuous paper, the distance from the top margin position on the present
page to the top margin position upon the next page is taken as the page length.
