Hi Wilfried,
Thanks, but I don't understand why you're sending this ticket which is about column size in a browse.
I will try to create a sample which demonstrate the bug.

Hello Alain,
my fault, here the sample for this ticket.

Hi, Wilfried,
I try your ticket, but it doesn't open the printer.

If I comment the line : oPrinter:lpreview := .T., it opens the printer, and I can print on the laser, or print in a pdf. But, obviously, the bug concerning the first page in portrait mode instead of landscape is always here.

There is a long time I haven't used Windows, and I don't know if it's possible, as under Linux, to print in a pdf. But the bug is always present when printing on a real printer, and I suppose and hope that with HwGUI Windows you're able to print this script on a printer. In this case you're perhaps able to see the bug, if it's the same as under linux.

Thanks

Hello Alain,
i need some info about the format of the scipt file "alpha.out".
First i thought, it is Post Script, i installed the GhostWriter and try to open the file.
but only the pure text is displayed.

Can you send more info (or some links in the Internet) ?
Or another idea ?

On Windows, i had no success to display the printout with Print2PDF.

With the WinPRN sample the printout appears OK, but
the WINPRN class has no method "LoadScript".
By calling the method "StartDoc(), file dialog for the PDF file
appeared and the PDF is created in the current directory.

I think, the information of "alpha.out" is processed by the printer driver.

Hi Wilfried,

alpha.out has been created using hwgui, so I don't understand why you are not able to use it. For me, there is no problem, except the problem with script landscape, where the first page is in portrait.
The problem is not a pdf problem, but an hwgui problem, as it occurs when printing in a pdf, or on the printer.
Have you tried under linux ?
Why are you trying to use WINPRN class ?
INIT PRINTER oPrinter"
Does this use WINPRN Class ?

I think, the information of "alpha.out" is processed by the printer driver.
* Probably, but when creating the script, it opens the print window, and if printing, there is not the default.
* It occurs only when opening the script that we save with hwgui.

If I have time, not for now, I will create a test program.

Hello Alain,
now continue the discussing:

• Have you tried under linux ?
  I tried both, Windows (with Microsoft Print2Pdf) and Ubuntu, but
  the EndDoc() method does not start the printout on Windows,
  LINUX starts, but with your reported format bug on the first page.

• Why are you trying to use WINPRN class ?
  The WINPRN class works also correct on Windows,
  see sample program WINPRN.PRG, so i want to check.
  See hwinprn.prg:
  METHOD New()
  ...
  ::oPrinter := HPrinter():New( cPrinter, .F., nFormType )
  ==> So the WINPRN class creates a HPRINTER object.
  After the printer dialog appeared, the print starts with
  the query to ask for the name of the PDF as target for
  the printout.

• INIT PRINTER oPrinter
  Does this use WINPRN Class ?
  No, see guilib.ch:

#xcommand INIT PRINTER <oprinter> ;
[ NAME <cprinter> ]</cprinter> ;
[ <lpixel: pixel=""> ]</lpixel:> ;
=> ;
<oprinter> := HPrinter():New( <cprinter>,!<.lPixel.> )</cprinter></oprinter></oprinter>

• If I have time, not for now, I will create a test program.
  I will wait for your new or modified sample program.

But i cannot detect the setmode(2,2) method (for example in NEW() method or
alpha.out), please explain.

I'll continue looking for the bus while waiting for your
answer.

Hello Alain,
for experiment i added (Ubuntu)
oPrinter:Preview()
after
oPrinter:LoadScript(cScript+".out")
The internal HWGUI print preview apears,
but all pages are not in landscape.
So i must understand,
how the script feature works.
For next step i will check differences in
hprinter.prg for GTK and Windows,
before continuing bugfixing.
On Windows, i added temporary
an new method:

METHOD StartDoc2() CLASS HPrinter
LOCAL nRes
::hDC := ::hDCPrn

nRes := Hwg_StartDoc( ::hDC, "HwGUIPrint" )

RETURN nRes

Before
LoadScript()
i added
oprinter:StartDoc2()

The query for PDF file name and the preview
apears, but no data are printed out, only boxes
and hear. also the PDF left empty again.

With this post i will inform you
about the recent state.

With regards

Hi Wilfried,

oPrinter:LoadScript(cScript+".out")
The internal HWGUI print preview apears,
but all pages are not in landscape.

That's exactly the problem I have. The first page is in portrait, which is not ok, but the others are in landscape as desired. But I say that printing just when creating the script, all the pages are in landscape. The problem occurs only when printing (or creating a pdf) using the out file.

For the pdf creation, I think it's a problem Windows. Under Linux, no problem.

Hello Alain,
i am very busy at this , so i will look for this ticket as soon as possible, SRI.
If you have any ideas, i will check it prompt.
Here i appended a file with some reports of analyising the problem on Windows,
because there no contents appeared.
