Recognize dot-matrix text that overlaps form elements

[Paul Gallagher]

My printer is old and needs to be adjusted regularly.  Instead of re-printing out all of our tickets to make it easy for me to digitize them, I'd like to be able to have tesseract ignore lines running through desired text.

This is the only text I need in the whole document, and is the only unique/identifying text. Here is an example:

I've tried photoshop to come up with a procedure to basically remove the blue line and leave the numbers, but I can't figure any way that works consistently.
