Appendix H
Single and Double Byte Character Font Mapping
Label format records with font code 9 in the b field of the Format Record header can specify
any of the following bitmapped or scalable fonts with the associated specification in the font
size/selection (eee height) field, as shown in the tables on the following pages.
Example:
1911u4000100010A0215134
The example above will produce a printed string consisting of the two Kanji characters
referenced by the two HEX ASCII pairs A0, 21, and 51, 34, on appropriately equipped
printers.
Example:
1911U4001000100P012P012<0x38><0x77><0x00>
The above example will produce a printed string consisting of the one 12 point Kanji
character referenced by the byte pair with hex values 38 and 77 on appropriately equipped
printers.

Double byte hex representation character strings terminate with two null bytes and a ,
i.e., 0x 00 00 0D. The Hex-ASCII representation is terminated with .
The alphanumeric portion (nn) of the scalable font specifiers, Snn, Unn, unn, numbering
system is a base 62 numbering system, 0, 1, 2…8, 9, A, B, C...X, Y, Z, a, b, c...x, y, z. For
scalable fonts the S designation signifies single byte characters and U designates double
byte. The lower case U counterpart signifies that print data in the label format record is in a
hex-ASCII format. Fonts that have been downloaded with designators of the form nn, where
nn are alphanumeric, as seen in the font size specifier (eee height) column below, may be
referenced in label format records by their upper or lower case specifiers as available.
However, fonts created for double-byte access cannot be accessed using Snn as the font
designator, and vice versa, single-byte fonts cannot be accessed using Unn or unn.

Downloading scalable fonts require specifying the font ID, a two character alphanumeric.
The S, or U, u used in referencing the font within label format records is not used in the
download specification. Attempting to utilize a scalable font with an inappropriate byte-size
designation (e.g. S on double byte or U, u on single byte) will have unpredictable results.
