ECC by Predetermined Value: (Default = 00x) This byte designates error correction levels by predetermined values. Valid predetermined values are 0-8. If the value of this byte is anything other than 0-8, the ECC level is set to 0. Predetermined values 00x 01x 02x 03x 04x 05x 06x 07x 08x Number of error code words 2 4 8 16 32 64 128 256 512 ECC can also be specified as a percentage. A valid non-zero ECC by Percentage will override ECC by Predetermined Value. See "ECC by percentage, bytes 1 and 2: (Default = 0000x)" on page 51. Units Enumeration for X Dimension: (Default = 02x) This byte sets the units used in specifying the X Dimension (the smallest element width). Supported values are 01x for 300 dpi units, 02x for 600 dpi units, and 03x for 1200 dpi units. X Dimension, bytes 1 and 2: (Default = 0005x) These two bytes set the X Dimension. To set the narrowest element to 5/300 of an inch, the Units Enumeration should be set to 01x, and these two bytes would be 00x and 05x. Y Ratio: (Default = 03x) This sets the bar height in terms of narrowest element width. If the X Dimension is 5/300 inch, then to set the bar height to 15/300 inch, this byte would be 03x. Truncated: (Default = 00x) This byte determines whether to omit the right row indicator and stop pattern. A value of 01x activates truncation. All other values disable truncation. Rows: (Default = 00x) This can be used to manually set the number of symbol rows. Both rows and columns must be 00x if using aspect ratio. Valid non-zero values are 03x to 5Ax (3 to 90 decimal). A value of 3 will be used in place of any specified non-zero value less than 3, and a value of 90 will be used in place of any specified non-zero value greater than 90. If columns is a valid non-zero value, and rows is 0, the Two-dimensional bar codes 50

ECC by Predetermined Value: (Default = 00x)
This byte designates error correction levels by predetermined values. Valid predetermined values are
0-8. If the value of this byte is anything other than 0-8, the ECC level is set to 0.
ECC can also be specified as a percentage.
A valid non-zero ECC by Percentage will override ECC
by Predetermined Value. See “ECC by percentage, bytes 1 and 2: (Default = 0000x)” on page 51.
Units Enumeration for X Dimension: (Default = 02x)
This byte sets the units used in specifying the X Dimension (the smallest element width). Supported
values are 01x for 300 dpi units, 02x for 600 dpi units, and 03x for 1200 dpi units.
X Dimension, bytes 1 and 2: (Default = 0005x)
These two bytes set the X Dimension. To set the narrowest element to 5/300 of an inch, the Units
Enumeration should be set to 01x, and these two bytes would be 00x and 05x.
Y Ratio: (Default = 03x)
This sets the bar height in terms of narrowest element width. If the X Dimension is 5/300 inch, then to
set the bar height to 15/300 inch, this byte would be 03x.
Truncated: (Default = 00x)
This byte determines whether to omit the right row indicator and stop pattern. A value of 01x
activates truncation. All other values disable truncation.
Rows: (Default = 00x)
This can be used to manually set the number of symbol rows.
Both rows and columns must be 00x if
using aspect ratio. Valid non-zero values are 03x to 5Ax (3 to 90 decimal).
A value of 3 will be used
in place of any specified non-zero value less than 3, and a value of 90 will be used in place of any
specified non-zero value greater than 90.
If columns is a valid non-zero value, and rows is 0, the
