Be wary about this. If one is doing sophisticated HP usage, it turns out that most "compatibles" fail the test. A couple years back, a university in England tested all the so-called compatibles and found that only the genuine HP machines passed the test. If you're tempted to get a clone of anything, make sure that you try before you buy. -dh --- Don Hosek To retrieve files from ymir via the | dhosek@ymir.claremont.edu mailserver, send a message to | Quixote TeX Consulting mailserv@ymir.claremont.edu with a | 714-625-0147 line saying send [DIRECTORY]FILENAME where DIRECTORY is the FTP directory (sans "anonymous") and FILENAME is the filename, e.g. "send [tex]00readme.txt".

The overall quality of HP emulations has gone up in the last couple of years. There is adequate technical documentation for everyone to be sure what behavior is required, and the LaserJet clone market has blossomed. Whatever clone printers some English academics were able to procure in 1988, you probably couldn't buy today. 2. I have a TI PS35 sitting right here. I have thrown all the HP files I know of at it, and it behaves exactly like a LaserJet Series II. There may be some lurking quirks, but I can't find them with normal use. 3. Nor is the average user likely to find any, simple because, given the choice of PostScript or HP at the flick of a button, most complex jobs are much better done with PostScript. HP is for when you HAVE to be a LaserJet for someone's hardcoded program or preformatted file. -- A doubled signature is the devil's work. ** Tom Neff <tneff@bfmny0.BFM.COM> -- A doubled signature is the devil's work. ** Tom Neff <tneff@bfmny0.BFM.COM>

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
