From: "Stephan v. Bechtolsheim" <svb@PURDUE.ARPA> According to today's Wall Street Journal (5/1/85) Xerox announced some new office automation type of equipment, including two laser printers - are these old hats with new labels? Anything of importance for the readers of laser-lovers? Stephan Bechtolsheim svb @ purdue ----------

From: KRAMER <billk%udel-cc-vax2.delaware@UDEL-LOUIE.ARPA> I have not seen the article, but XEROX was scheduled to announce a 10 page a minute and a 24 page a minute printer on 1 May. The 10 page a minute printer holds 250 sheets for input and 100 sheets for output. It was suppose to have 2 resident fonts, with additional fonts available, and of course downloadable fonts. It has a collation option so the pages are stacked properly, and a copier option. The memory is 128Kbytes, and is expandable. It does bitmap graphics with a resolution of 150 x 150 for a 1/2 page and 75 x 75 for a full page. The 24 page a minute printer has 3 trays for 2000 pages of input, and 500 pages of output. It has a 10 Mbyte winchester for spooling and fonts and a 5 1/4" floopy for loading, forms, etc. It is the same engine as the 2700 - so the quality should be similiar to the QMS 2400. It will be able to use 11 by 17 inch paper and have all points addressable bit map graphics. Both models have "line drawing" abilities, but from what I can figure out that means only horizontal and vertical lines, not arbitarily positioned vectors. Interfaces include IBM (bisynch and SNA), centronics dataproducts, RS232 and ethernet (I am not sure the exact particulars on mixing and matching).

From: SStrasen.es@XEROX.ARPA Xerox did indeed announce two printers on May 1, together with a lot of other Xerox Network Systems equipment. The 10 page per minute model is called the 4045 Laser CP while the 24 page per minute model is called the 3700. Your message about them was quite accurate, but there were a couple of points about the 4045 CP where I would like to avoid some possible confusion. The base model does have the 2 resident fonts you mentioned. You can also add up to 4 additional font cartriges each of which contains up to 9 additional fonts (depending on size) and these fonts together with the base fonts can then all be accessed at the same time. Together with the downloadable fonts this means that a single document can use up to 128 fonts. (2 standard fonts, 36 fonts from the font cart- ridges, and up to 90 downloaded fonts). As you know, bitmap images take quite a bit of memory to store, so the bitmap image or graphic imaging capability is a function of the memory size installed. With the optional 1 Megabyte memory the 4045 CP can handle a 5"x7" image at 300x300 spots per square inch or some combination of smaller graphics whose area is the same. It can also handle a full page bitmap at 150x150 spots per square inch. By the way, the life expectancy of the 4045 CP is approximately 600,000 prints, or 10,000 prints per month for 5 years.
