Configuring the Printer 2-5
Supply Control Commands
The commands in this section control how the printer uses black-mark supplies.
Look at your supply (distance between black marks, existence of any preprinted
text, etc.) before you begin. You may have to use the black mark search
command multiple times if the marks are farther apart than the maximum search
allows. To use these commands:
1. Set the sensitivity of the sensor search mechanism detecting the black
mark (ESC QQ command).
2. Move the supplies forward (ESC QF command) or backward (ESC QB or
ESC QJ commands) to find the black mark.
3. Wait for a response from the printer (found or not found).
4. Send a data stream with printing commands.
