I see you found your solution but for the record there are ps2txt and ps2ascii you can use to display these as well as this useful article I used in the past:
https://www.cs.waikato.ac.nz/~ihw/pa...tract-Text.pdf
It prepends a short and sweet extra postscript function to the original postscript which redefines the show methods to give you text output that would be easier to parse.
FWIW, I find working with "ps printer device" can extract text electronically that is very hard to get to in other ways without a scanner.
