IBM SUREMARK TF6, User Manual

Page: 138 / 244

Remarks:
These messages can be positioned on the page using the commands for
setting positions.
Decimal values are shown, but all parameter values (logo number, n1, n2)
must be hex values when sent to the printer.
The dot density of these messages is specified when the message is
printed. See “Print predefined graphics (logo) command” on page 159.
The total number of data bytes defined for all (up to 40) defined graphics
messages must be less than 65 376 in all models except TI8 and TI9, in
which the value is user-defineable.
If the parameters logo# , n1 , or n2 are out of range, the command is
discarded and its remaining data is processed as print data.
This command should be sent only when the data buffer is empty. See the
description of bit 6 in “Status byte 2” on page 185.
Images for the thermal logo commands will be defined by one-dot-high rows
(horizontal slices), and the impact will be defined by eight-dot-high rows
(vertical slices).
This command can be used to print signature captures at the printer.
1. Capture the signature as a bitmap.
2. Convert the bitmap to a series of graphics (logo) messages.
3. Hold the printer’s buffer.
4. Send the graphics messages to the printer.
5. Release the printer’s buffer.
Note: For a thermal graphic message that is 24 dots high, across the page (n1 =
72, n2 = 3) takes over 2000 bytes of data.
Example: n1 = 2 & n2 = 2
