IBM 1xR Printer User Manual


 
determine the logos that have been stored in the printer. 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 67.
The total number of data bytes defined for all defined graphics messages
depends upon the amount of memory the user has allocated. See “Memory
allocation” on page 18.
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 “Erase flash sector” on page 30.
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).
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
