Hello Antonio,

I have a printroutine that prints several pages with plantinformation. On every page I want to have the information on the same place. The number of pages is depending on the length of an array. I had a working function, but now I have a new printer and everything shifts to other position.

How can i make a print working on every printer the same.

Code: Select all

PUBLIC nPage
PUBLIC nPagePx := 815

PUBLIC oPrn:=TPrinter():new(0,0,0,0)

oPrn:SetLeftMargin(0)
oPrn:SetRightMargin(0)
oPrn:SetTopMargin(0)
oPrn:SetbottomMargin(0)
oPrn:SetPaperName("A4")
oPrn:AutoPage(.T.)
oPrn:SetSize( oPrn:pageWidth()-56 , (oPrn:pageHeight()) * LEN(aPrintArray))

FOR nPage = 1 TO LEN(aPrintArray)
    nRow := 56 + ((nPage-1)*nPagePx)
    @ nRow, nCol SAY oSay PROMPT cLatijnNaam OF oPrn SIZE 480, 40
        oSay:Setfont("Arial",20 )
        oSay:setTextColor(0,51,0,100)
    @ nRow+30, 285 IMAGE oImg OF oPrn SIZE 250, 250 FILENAME cFoto
        oImg:SetFrame()
NEXT
oPrn:run()

IF I vary nPagePx I can make it work, but I think this is depending on the printer installed. I want it to work with every printer/computer

Hello Antonio,

I am sorry, but I don't understand this code.
(I speak English, but not French

)

I hope you can make me an exaple on how to use this.

Please add this line and test it with different printers and let me know what you get:

oPrn:AutoPage(.T.)
MsgInfo( oPrn:pageHeight() )
oPrn:SetSize( oPrn:pageWidth()-56 , (oPrn:pageHeight()) * LEN(aPrintArray))

Hello Antonio,

With several printers I get the same output: 841. According to my calculation that should be right, because I think 10 mm = 28,33 px.
So an A4 paper of 210*297 mm gives (21*28,33) 595 px width and (29,7*28,33) 841 height.

But if I use these numbers to set a new page, it doesn't fit...

How many elements of aPrintArray would you like to fit in one page ?

I think it is the logic of your code what fails

Posted: **Sun Sep 23, 2018 11:33 am**

Hello Antonio,

The number of elements that I want to print on a page very every page. But some elements always comes back on all the pages. I have made a little sample that shows the problem. If you click 'print' and browse through the pages in the preview you can see that all the lines shifts a bit every page. When I increase or decrease the value nPagePx I can make it not to shift as much, but I don't think that this is a good solution. As I told before, on one printer the value of 819 works great, on another printer I have to decrease it to 813.

Hello Antonio,

Did you have any time to look at my printing sample and how to get everything on the same position every page?

Posted: **Tue Oct 02, 2018 6:49 pm**

René,

I am checking it

Posted: **Tue Oct 02, 2018 8:48 pm**

René,

This way I am able to properly print on the first page though I get an empty (and undesired) second page:

Anyhow, using this code I am unable to print more than one page...

Code: Select all

#include "FiveMac.ch"

static oPrn

function Main()

   local oDlg

   DEFINE DIALOG oDlg TITLE "Printer test"

   @ 40, 40 BUTTON "Print" OF oDlg ACTION Print()

   ACTIVATE DIALOG oDlg

return nil

function Print()

   oPrn = TPrinter():New()

   oPrn:SetLeftMargin( 0 )
   oPrn:SetRightMargin( 0 )
   oPrn:SetTopMargin( 0 )
   oPrn:SetBottomMargin( 0 )
   oPrn:SetPaperName( "A4" )
   oPrn:AutoPage( .T. )
   oPrn:SetSize( oPrn:PageWidth(), oPrn:PageHeight() - 60 )

   oPrn:Run()

return nil

function PrinterPaint()

   local nStep, n, nLine := 1

   nStep = ( oPrn:PageHeight() - 60 ) / 30 // 30 lines 

   for n = 0 to oPrn:PageHeight() STEP nStep
      @ n, 0 SAY Str( nLine++ ) OF oPrn
   next

return nil

Hello Antonio,

According to the sample 'testprint' we have to set pageHeight() to the height of the desired pages. As long as we set this to the height of one page there will never be a next page.

Is it not possible to build in some functions like StartPage() and EndPage() that starts and ends a page with settings set by pageheight()?

Posted: **Thu Oct 04, 2018 8:29 am**

René,

Manuel Alvarez and I are reading Apple documentation about it:

https://developer.apple.com/library/arc ... ation.html

We may need some time to implement StartPage() and EndPage().

In the meantime, if you can keep using your current solution, that would be fine. Thanks

Posted: **Thu Oct 04, 2018 10:50 am**

René,

Manuel has implemented a new Class TPrinter Method GetASizePrintable() that is working great!

Here you have an example printing X pages:

Code: Select all

#include "fivemac.ch"

static oPrn

function Main()

   local oDlg

   DEFINE DIALOG oDlg TITLE "Printer test"

   @ 40, 40 BUTTON "Print" OF oDlg ACTION Print()

   ACTIVATE DIALOG oDlg

return nil

function Print()

   local aSize

   oPrn = TPrinter():New()

   oPrn:SetLeftMargin( 0 )
   oPrn:SetRightMargin( 0 )
   oPrn:SetTopMargin( 0 )
   oPrn:SetBottomMargin( 0 )
   oPrn:SetPaperName( "A4" )
   oPrn:AutoPage( .T. )

   aSize = oPrn:GetASizePrintable()
   oPrn:SetSize( aSize[ 1 ], aSize[ 2 ] * 3 ) // 3 pages

   oPrn:Run()

return nil

function PrinterPaint()

   local nStep, n, nLine := 1
   local nHeight := oPrn:GetaSizePrintable()[ 2 ] * 3 // 3 pages

   nStep = nHeight / ( 30 * 3 ) // 30 lines * 3 pages

   for n = 1 to nHeight STEP nStep
      @ n, 0 SAY Str( nLine++ ) OF oPrn
   next

return nil

René,

We already have a first implementation of Class TPrinter Methods() StartPage() and EndPage().

Here you have an example of use. Hopefully the modified Class TPrinter does not break your existing code:

printer.prg // A new example of the FiveMac enhanced Class TPrinter

Code: Select all

#include "FiveMac.ch"

function Main()

   local oDlg

   DEFINE DIALOG oDlg TITLE "Printer test"

   @ 40, 40 BUTTON "Print" OF oDlg ACTION Print()

   ACTIVATE DIALOG oDlg

return nil

function Print()

   local n, oPrn := TPrinter():New()

   for n = 1 to 10 // ten pages
      oPrn:StartPage()
      
         oPrn:Say( 0, 250, "Header " + Alltrim( Str( oPrn:nPages ) ) )
         oPrn:Say( oPrn:LastRow(), 250, "- Page " + Alltrim( Str( oPrn:nPages ) ) + " -" )

      oPrn:EndPage()
   next

   oPrn:Run()

return nil

Hello Manuel and Antonio,

Thank you very much for all this work. I think with some addaptions this will work great. For now I miss the following:

setting fontname -size and -color of the say
printing images

If this is build in I can work with the new Class TPrinter.
