IBM TF7, TM7, TI5, TG5 manual Proportional Font, Defined as

updated March 18, 2002

Defined as:

X'1B26014848 C0C0C0C0C0C0C0C0C0C0C0C0C0C0FFC0FFC0F C0C0C0C0C0C0C0C0C0C0C0C0C0C0C0C0C0C0'

The above statement defines character X'48' as an ’H’.

Note: The number of data bytes = 2 × dot height (20) = 40 bytes.

Proportional Font

RS-232 Syntax:

ESC & s n m data or X'1B;26;s;n;m;data'

where:

sThe character set being defined.

1 User-defined thermal code page 1.

3User-defined thermal code page 3.

nThe beginning ASCII address of the characters being defined.

mThe ending ASCII address of the characters being defined.

data The height and width of the character, and the matrix pattern for the data. The number of data bytes is (m−n+1) × (2+wb×32). wb is defined in the MCT command.

Purpose:

To download and print proportional fonts (True Type fonts) in the thermal station. Each character in the code page has its own unique width and height. The matrix must be within the following ranges:

Width 8 ≤ width ≤ 32

Height

8 ≤ width ≤ 32

Remarks:

vProportional and standard fonts may be used on the same line. If both types of fonts are used on a line, you would probably use proportional fonts for the description and resident fonts for the amounts.

vFor alignment, a command that will allow right and left alignment on the same line may be used. This will allow the user to align a column (decimal point) on the right, and still be left-aligned. (See “Align Positions” on page 134.)

vOnce characters are downloaded to the printer, they remain valid until you redefine them. This is true even if power to the printer is removed.

vBefore the characters are defined, the sector of the flash EPROM which stores this data must be erased. (See “Erase Flash EPROM Sector” on page 121.)

vThere is no way to redefine one character only. You must redefine a whole code page.

vIf the parameter s, n, or m is out of range, the command is discarded and the remaining data is processed as print data.

vThis command should be sent only when the data buffer is empty. See the description of bit 6 in “Status Byte 2” on page 161.
