Your file distilled into a complete pdf booklet (107 pages) after I removed the printer escape characters that had been prepended and appended.
In looking at the PostScript code the structure of the code layout is part of the problem:
the occurrance of "-2 vmreclaim" several times per page, followed by a redefinition of the user procedures could be cleaned up so that the user procedures are defined once in the prolog of the document and the "-2 vmreclaim" statements are removed altogether. "-2 vmreclaim" turns off the automatic garbage collection, normally this would be done for interactive or monitoring functions, but in this context I don't know why that would be of benefit.
After commenting out the "-2 vmreclaim" like "%% -2 vmreclaim" throughout the document, distiller rendered the program much, much faster, and I would guess that your printer will render it completely and faster as well.
