The first problem is that, being in Europe, we use A4 size paper and
the transcript programs apparently clip to 8.5 x 11. I first
encountered this in enscript -r. This resulted in the bottom line
being almost completely clipped and also the first character from each
line was almost entirely gone. Changing the following definition in
enscript.pro from
/Landscape{90 rotate 0 -15840 translate}def
to
/Landscape{90 rotate 90 -15705 translate}def
has solved that problem. However, I still lose the bottom line when
I lpr to the printer (which is a LaserWriter+). So my first questions
are:
Did I fix the right part with regards to enscript?
Where do other fixes need to go to cope with A4 paper?
Part 2. Ditroff stuff.
This part of the distribution doesn't seem to have been built correctly.
And the instalation manual is quite vague in this area. Also, my
knowledge of {di}troff is about nil. Can somebody tell me what is
supposed to go where so that things (psdit, etc) work like the man
pages say they do? Also, we have the DWB stuff from Death Star and we
have a 4.3BSD 785. Has anybody gotten this stuff to build and run? If
so, how? As you can see, we are just getting things put together here.
If you have any information that will make this less traumatic, please
let me know.
Thanks greatly

Not quite - part of your trouble comes from the LaserWriter itself. There are two lots of clipping going on in the printer: 1) Hardware clipping. Based on the notches in the size of the paper tray, the printer hardware chooses an area outside of which the laser is inhibited, in order to avoid printing off the edge of the piece of paper. 2) Software clipping. The page type you use (A4, letter, legal etc) controls the amount of memory that the interpreter uses for its framebuffer. This is inescapable low-level clipping: drawing outside of the framebuffer has no effect. This is just software and has not interaction at all with the hardware clipping. The TranScript stuff usually does no extra clipping at all, so you are losing black marks on the paper because of one of the above. You may be surprised to hear that I have NEVER yet met a LaserWriter or LaserWriter+ where the default software clipping region is entirely within the hardware clipping region. In other words, the bitmap the PostScript prepares is being clipped by the printer electronics. To find out what is happening on your printer, try the following: %! initclip clippath % find the edge of the framebuffer gsave 0.75 setgray fill % fill it in gray grestore 72 setlinewidth % lines 1 inch wide stroke % draw a black border showpage If you do this, you will get a large gray rectangle with edges about 0.5 inches wide: the 1 inch think line is centred on the boundary of the framebuffer, so the outer 1/2 inch is removed by the software clipping. However, you will probably also find that one edge is not quite wide enough BECAUSE IT HAS BEEN CLIPPED BY THE HARDWARE. This is the edge where the bottom line of your enscript output has got lost. To fix it, you will need to adjust the margins stored in the EEPROM - look in the manual for details of the "setmargins" command, but it will be something like %! 0 serverdict begin exitserver statusdict begin 0 -2 8 mul setmargins % set new top & left margins ------------ As for the other problems, we have AT&Ts version of DWB running with TranScript 2.0 on a VAX 11/750 under BSD 4.2 + NFS 3.0, so I guess you could mail me with a more detailed list of your woes. -- William Roberts ARPA: liam@cs.qmc.ac.uk (gw: cs.ucl.edu) Queen Mary College UUCP: liam@qmc-cs.UUCP LONDON, UK Tel: 01-980 4811 ext 3900
