HP printer printing code not text

Hey was frustrated with using a hp deskjet 648c with windows since it wouldn't print a thing and it constantly jammed up so I took it to my mac. But with my mac it spits out around 20 and a half blank pages before it starts to print code not text but code I presume its the code that the computer is sending to the printer for it to decode and print here is alittle taste:

Code:

14 dict begin/fontname /rjboxg+arialnarrow-bold def
/painttype 0 def
/encoding 256 array 0 1 255 {1 index exch/ .notdef put} for
dup 33 /space put
dup 34 /A put

and it continues I used the drivers on 10.5 cd running 10.5.1 just saw .2 released but don't think that it will improve anything read the list on printing but ill give that a go later.

any suggestions?
