Please help the PS novice ... thanks :-)

PRINTER:
	DataProducts LZR1260 (Adobe engine ... supposedly), version 47.0

FILE:
	"lasedoctor" ... origin netland, version 1.0.0

SYMTOM:
	send file to printer in batch mode ... error is as follows:
		%%[ Error: rangecheck; OffendingCommand: cvs ]%%
		%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%

Change printer to interactive mode ... error is still there, but file prints.
Additionally:
1) the string "cvs" is repeated later on ... but not flagged as an error.
2) Brother HL8-PS & Apple NT do not "barf"

returned data is below :
