23Source code for a simple program that translates ASCII files into PostScript. The
24only important change, besides the restructuring that's been applied to all the
25translators, is the addition of the -r option that controls how carriage returns
26are handled. As in previous versions the default behavior is to ignore carriage
27returns. The two other choices are to return to column 1 (-r1 option) or treat
28carriage returns as newlines (-r2 option). You can modify the default behavior by
29changing the initialization of crmode (near line 98) in postprint.c.

31Things have been tuned for PostScript printers running at 9600 baud, and may not
32be optimal for fast printers running at higher baud rates. A few simple changes
33here and in ../postscript/postprint.ps could help if throughput seems to be
34lacking:
35
36 1) Near line 755 in postprint.c change
37
38 fprintf(fp_out, ")%d L\n", stringstart-1);
39
40 to
41
42 fprintf(fp_out, ")%d %d L\n", stringstart-1, stringcount);
43
44 Then change the definition of procedure L in ../postscript/postprint.ps
45 to,
46
47 /L {
48 {charwidth mul currentpoint exch pop show} repeat
49 linespace add dup 0 exch moveto
50 } bind def
51
52 2) Change the upper limit test near line 694 (procedure spaces()) in postprint.c
53 from 6 to something bigger. Output files will be larger, but will run faster
54 when they get to the printer. Should help if you're running at 19.2KB or
55 higher.
56
57 3) Adjust the scaling set in procedure setup in ../postscript/postprint.ps so
58 1 unit corresponds to the line spacing. Then replace 'linespace add' in
59 procedures l and L by '1 sub'. It's a little tricky, but I've tried it and
60 it does work.
