               EXCHANGE OF EXPERIENCE



               (C) Yuri Buravtsov (OneSOFT)


            Printing out


  Long ago, when I have only appeared a printer, I was eager to 
learn control codes that can change the print settings, and 
general printing. And I was learn to type in every one of the 
system IS-DOS. The result was this document.



  This information is intended for those
Persons who do not want to spoil the extra sheets of paper, 
check out how the printer prints in deriving it Tectah. Print 
will in A4 format on the narrow side.



  First, we define the number of rows. When
select normal height characters you're right
select the number of lines on paper to
eighty. Moreover, if you're using
sheet printing, the number of lines approved by the spacing: it 
should chosen as follows:



          2160 / [number of lines]

moreover, it is desirable that this relationship was no 
fractional remainder, because printer with the Add

format for the passage in 2160 of printed products (MS 6313 
new, and others) will accumulate extra lines, printed on one 
the following pages. Simply put, here Table:



                                                   Table 1

     DEPENDENCE Line spacing the number of rows


     rows 15 16 18 20 24 27 30 36 40 45 48 54 60 72 80


     Int. 144 135 120 108 90 80 72 60 54 48 45 40 36 30 27



  Selecting the appropriate settings, safely
can print. Things are somewhat
otherwise, if you suddenly decided to print the index - the 
line spacing is chosen significantly smaller:



                                               Table 2

                    INDEXING MODE


        The number of rows 90 108 120 135 144 180


        Mezhstr. Int. 24 20 18 16 15 12



  Now it will go on printing in two columns. To fine print in 
various print modes, ie not got the edge and not wasting too 
much paper is the following table: 


                                                      Table 3

    DEPENDENCE ON THE TYPE Column Options Print Density


  Density of Compacted Small Small Normal + seal.


  Full width 80 96136160

  line


  Permitted 70 84119140

  line width


  The column width is 33 40 57 68

  in iS-EDIT


  Between columns 4 4 5 4


  The column width is 37 44 62 72

  in iS-PRINT



  So. All sizes of this table are given in
symbols, which implies easy to read a text editor program
Print. When printing line width should be chosen on the basis of


        [Width of the editor iS-EDIT] + [Column spacing]

or even from the table the values ​​of the last column.


  Of course, that this your opportunity
not limited to, I'm just on my own experience I can confidently 
say that the data from the tables, at least for me, are the 
most be acceptable and comfortable.



  Although, of course, tastes differ ...


  In one of the following articles will be considered control 
codes EPSON-compatible printers. 


  Your questions and suggestions I will listen to
address:


   Yuri Burawtsow, 812/01.14 @ SpbZxNet,

as well as be able to answer them as soon as possible.
