Generating Label Formats
E-Class DPL Programmer’s Manual 63
ffff: Row Position
The lower left corner of a label is considered the “home position”, see Figure 8-1. The row
position field is a vertical coordinate that determines how far above the home position the data is
to be printed. Field data is interpreted in hundredths of an inch or tenths of millimeters.
gggg: Column Position
This field is a horizontal coordinate that determines how far to the right of “home position” the
data will be printed. Appendix J lists the maximum values of the gggg field.
hhhh: Optional Scalable Font Height
The height of a scalable font can be specified in two ways, points or dots. To specify the height
in points the first character of the field is a ‘P’ followed by the number of points, 004 to 999
points. To specify the size in dots, all four characters must be numeric. This field must be
specified for scalable fonts. See note below.
iiii: Optional Scalable Font Width
The width of a scalable font can be specified in two ways, points or dots. To specify the width in
points, the first character of the field is a ‘P’ followed by the number of points, 004 to 999 points.
To specify the size in dots, all four characters must be numeric. This field must be specified for
scalable fonts. See note below.
Note: To ensure that the data stream is portable to different Datamax printers, specify the
font size in points. If the font is specified in dots, it will output differently on printers with
different DPI/MMPI resolutions. There are 72.307 points per 1 inch (2.847 mm).
jj…j: Data Field
The final field contains the data that will actually be printed on the label. A string of data can be
up to 255 characters in length, (except when using the PDF 417 barcode, which may be up to
3000 characters long) ending with a carriage return. Characters placed in the data field will be
printed as long as they fall within the physical range of the printhead. See Appendix J for a
listing by printer.
Record Structure Types
Each of the six record types has its own field structure as described in the following tables. These
record types allow quick reference to the field types and their valid data inputs for the field. There
are similar, but unique, record structures for each: internal bit-mapped fonts, internal smooth fonts,
downloaded bit-mapped fonts, scalable fonts, bar codes, images, and graphics. The field location
identifiers in the tables that follow are the same as those in Table 8-3.
1. Internal Bit-Mapped Fonts
This record type is used for internal bitmapped fonts (see Tables C-1, C-2 and C-3).
When a 0 through 8 is entered in field b, then the height field eee is not used. The bitmapped fonts
include 8 different fonts (see Appendix C). The character mapping for these fonts is shown in
Appendix A or a subset thereof.
