Need Help - Strange Print Output HP 950 AIO

My HP 950CSE (All-In-One) is suddenly printing two extra pages along
with normal printout(s), no matter the number of pages being printed.
The pages contain what looks to me like some sort of (?printing?)
script.

For example - page one starts out
errordict begin /handleerror {error begin newerror { /newerror false
....etc..........
page two starts out
xmin ymax 1.5 inch sub lineto
closepath
....etc..........
Helvetica findfont .2 inch scalefont setfont
....etc.....

I have no idea why this started. Can anyone advise how to get rid of
it?

Thanks

Jethro
