Hello, I get PostScript from someone (comp.sources.unix) but I don't have X11-Windows. Later, I found a reference file at Sri-Nic node (service@sri-nic.arpa). It called RFC1013 file. It have many information about X11 windows protocols. Is RFC1013 compitable with UNIX X library??? If, not, Is it PD or Properitory?? If properitory, please know me that where company sells it include address and price, etc... If PD, please know me that who distribute it includes address.. Please reply me directly. Thanks. -- Tim Stark +==============================================================================+ | Timothy Stark | BitNet: 11TSTARK@GALLUA.BITNET | | Gallaudet University | Internet: 11TSTARK%GALLUA.BITNET@CUNYVM.CUNY.EDU | | P.O.

Now that there are several PostScript clones around or about to be around, we printer-buyers have a problem: How do you know if a clone measures up? When I first thought of this, the only answer I could see was to try printing stuff on different printers to see what would happen, but this has some difficulties: visual fatigue, human error, blah, blah... It then occurred to me that one might be able to do better: the "framedevice" operator is given a proc as argument that is called ""to cause the contents of the frame buffer to be transmitted to the physical output device" (PLRM pp. 162) If we knew what this proc was expecting as arguments, we could maybe arrange for it to send a representation of the raster frame buffer back down the communications link, and then do something (heaven only knows what) to verify that you get the same bits out when you put the same bits in. Has anyone tried this approach, or come up with something else in the way of validation? I agree that the resultant bitmaps (even at 300 DPI) need not *exactly* match between an Adobe Postscript and a clone printer -- particularly if they use different technology engines (so that one would want some difference). On the other hand, the relative darkness of different areas of the pages should be alike, and one could go on from there.

You could grab all the fonts off the printer that way. Since fonts do not enjoy copyright protection in the US, printer manufacturers have to protect their fonts by encoding them in proprietary format in ROMs. Also, you'd need a fast channel like AppleTalk or a Centronics interface for this to be practical.
