Whatever clone printers some English academics were able to There are still significant problems with Version 47.0a and 47.0c Adobe HP emulations. One of the really intersting things that I found on the version 38.0 hp interpreter in the PS-JET product, was the behavior of the code that sets the number of lines per inch. The HP documentation implies that you can set this to any number. Under the Adobe emulation, you can. If you say you have 66 lines per inch, it does 66 lines per inch. On a true HP, however, there are restrictions. If you say 66 lines per inch, you get 6 lines per inch. Indeed, it appears that the HP emulation obeys only discreet values for LPI. Cheers Woody
