Oscar,

Please try this code:

MsgInfo( StrTran( GetProfString( "Devices" ), Chr( 0 ), Chr( 13 ) + Chr( 10 ) ) )

and post here your result

[ORibeiro]

Linares,

Result:

CutePDF Writer
Fax
PDF reDirect Pro v2
Argox OS-214tt PPLA
\\OASYS4\Samsung SCX-4200 Series
Enviar para o OpenNote 2007

Ok, so if you do:

PRINTER oPrn TO "Samsung"

that would be enough to select the Samsung printer

[ORibeiro]

If I do this, ::hDC returns zero and does not print.

[Antonio Linares]

Oscar,

In Class TPrinter, function PrintBegin() we search for the printer based on the provided cModel name:

Code: Select all  Expand view  RUN

     if ( nScan := Ascan( aPrn, { | v | Upper( xModel ) == Upper( v ) } ) ) == 0
         nScan = Ascan( aPrn, { | v | Upper( xModel ) $ Upper( v ) } )
      endif

Please place a MsgInfo( nScan ) there to see what is going on there with your printer.

If you write To "Samsung", then: nScan = Ascan( aPrn, { | v | Upper( xModel ) $ Upper( v ) } ) should find it.

[ORibeiro]

Results:
nScan = 6
cDevice = \\OASyS4\Samsung SCX-4200 Series,winspool,Ne04:

But printing out the PDF reDirect.

Do you have another idea?

Thanks

[Antonio Linares]

In Class TPrinter method New() then this code should be ok:

Code: Select all  Expand view  RUN

METHOD New( cDocument, lUser, lPreview, cModel, lModal, lSelection, cFile ) CLASS TPrinter

   local aOffset
   local cPrinter

   DEFAULT cDocument  := "FiveWin Report" ,;
       lUser := .f., lPreview := .f., lModal := .f., lSelection := .f.

   if lUser
      ::hDC := GetPrintDC( GetActiveWindow(), lSelection, PrnGetPagNums() )
      if ::hDC != 0
         cModel = ::GetModel() + "," + ::GetDriver() + "," + ::GetPort()
      endif
   elseif cModel == nil
      ::hDC  := GetPrintDefault( GetActiveWindow() )
      if ::hDC != 0
         cModel = ::GetModel() + "," + ::GetDriver() + "," + ::GetPort()
      endif
   else
      MsgInfo( cModel )  // here
      ::hDC = PrinterDcFromName( , cModel, )  
      MsgInfo( ::hDC )  // here
   endif

Please let me know if your code goes through there and what you get on the MsgInfos()

Oscar,

PRINTER oPrn TO "Samsung"

that would be enough to select the Samsung printer

If I do this, ::hDC returns zero and does not print.

Try using the exact printer name:

PRINTER oPrn TO "Samsung SCX-4200 Series"

[Antonio Linares]

Results:
nScan = 6
cDevice = \\OASyS4\Samsung SCX-4200 Series,winspool,Ne04:

But printing out the PDF reDirect.

Do you have another idea?

Thanks

Please try this code:

Code: Select all  Expand view  RUN

PRINT oPrn TO "Samsung"
   PAGE
      oPrn:Say( 1, 1, "Hello" )
   ENDPAGE
ENDPRINT
 

that code should work fine. Please try it and let me know if it works fine, thanks

[ORibeiro]

I found! eureka

The problem is the command PrnGetName().

Please test with the following code within an application and run it twice: Perform close viewing and rerun without leaving the application.

Code: Select all  Expand view  RUN

PRINT oPrn NAME "TESTING"+" ("+ PrnGetName() +")" PREVIEW MODAL TO "Samsung"
   PAGE
      oPrn:Say( 1, 1, "Hello" )
   ENDPAGE
ENDPRINT
 

The first time he respects the printer sent in command TO "Samsung", the second time he returns to the Default Windows.

I use this command on all reports of my system to display the title of the selected printer viewer.

How can I solve this?

[ORibeiro]

Please, test it:

Code: Select all  Expand view  RUN

GetPrintDC( GetActiveWindow() ) // -> Please, change de default printer in this point

MsgInfo( PrnGetName() ) // See the new printer selected above

PRINT oPrn NAME "TESTING"+" ("+ PrnGetName() +")" PREVIEW MODAL
   PAGE
      oPrn:Say( 1, 1, "Hello" )
   ENDPAGE
ENDPRINT

MsgInfo( PrnGetName() ) // See that printer go back to the default in windows

 

[Enrico Maria Giordano]

Please try to remove the PrinterEnd() call from TPrinter End() method. It seems to solve the problem. But I don't know if there will be side effects.

Antonio, what is it for?

EMG

[ORibeiro]

Yes Enrico,
Thanks a lot.
This change solve my problem.

Linares, any side effects to remove this line?


Another existing problem: In the same example, change the printer on button of the viewer and see the result. The system will disconnect the printer.

Code: Select all  Expand view  RUN

GetPrintDC( GetActiveWindow() ) // -> Please, change de default printer in this point
MsgInfo( PrnGetName() ) // See the new printer selected above
PRINT oPrn NAME "TESTING"+" ("+ PrnGetName() +")" PREVIEW MODAL
   PAGE
      oPrn:Say( 1, 1, "Hello" )
   ENDPAGE

// CHANGE THE PRINTER in the button of the Report Preview

ENDPRINT
MsgInfo( PrnGetName() ) // See that printer go back to the default in windows
 

[Antonio Linares]

Oscar, Enrico,

Yes, PrinterEnd() is cleaning all the printer setup. We could remove it from METHOD End()

I am doing some tests, thanks
