Name of a print job is missing [message #5422]

When printing Report object, the name of the job is missing in the list of pending jobs.

Fix is simple:

In Report/Reportdlg.cpp change Print() from

bool Print(Report& r, int i, const char *_name) {
	PrinterJob pd;

bool Print(Report& r, int i, const char *_name) {
	PrinterJob pd(_name);

How do you print directly to default printer without the popup printer dialog?

Thanks,

Do not call Execute for PrinterJob.

Hi Mirek,

I tried the following in my code:

PrintJob pd("test");
Draw& w = pd.GetDraw();
w.StartPage();
w.DrawDrawing(500, 500, sz.cx, sz.cy, r.GetPage(0));
w.EndPage();

but it does not print anything. Am I missing anything?
btw, r = Report;

Thanks,

Laurice

My solution to direct printing:

//CtrlLib/CtrlUtil.h - above struct Win32PrintDlg_; and #ifdef:

Draw * GetDefaultPrintDraw(const String &a_name);

//CtrlLib/PrinterJob.cpp In windows part after PrinterJob& PrinterJob::CurrentPage(int i):

Draw * GetDefaultPrintDraw(const String &a_name)
{
	One<Win32PrintDlg_> pdlg = new Win32PrintDlg_;
	PRINTDLG& dlg = *pdlg;
	dlg.Flags = PD_DISABLEPRINTTOFILE|PD_NOSELECTION|PD_RETURNDC|PD_HIDEPRINTTOFILE
		|PD_PRINTSETUP|PD_ALLPAGES|PD_RETURNDEFAULT;
	dlg.nFromPage = 1;
	dlg.nToPage = 1;
	dlg.nMinPage = 1;
	dlg.nMaxPage = 1;
	dlg.hwndOwner = GetActiveWindow();
	dlg.hDevNames = NULL;
	dlg.hDevMode = NULL;
	if(!PrintDlg(&dlg)) return false;
	return new PrintDraw(dlg.hDC, Nvl(a_name, Ctrl::GetAppName()));
}

//After last method, but in POSIX section:

Draw * GetDefaultPrintDraw(const String &a_name)
{
	String options;
	PrinterDlg dlg;
	options.Clear();
	options << " -d " << ~dlg.printer;
	options << " -o media=" << ~dlg.paper << "," << ~dlg.slot;
	if(dlg.landscape)
		options << " -o landscape";
	options << " -o number-up=" << ~dlg.npage;
	options << " -n " << ~dlg.copies;
	if(dlg.collate)
		options << " -o Collate=True";
	
	Size pgsz;
	pgsz.cx = 6000 * 210 / 254;
	pgsz.cy = 6000 * 297 / 254;

	PrinterDraw *pd = new PrinterDraw(pgsz);
	pd->options = options;
	return pd;
}

Maybe it has a lot of code not needed, but I didn't work too much with it.

Well, but this does not allow to set orientation....

I am currently looking into problem. The trouble is that once hDevMode is set (to set landscape mode), it is no more possible to call PrintDlg with PD_RETURNDEFAULT...

Hi Mirek,

So how do I use this in my code?
I'll call this method directly ?

Please shed a li'l more tip.

Thanks,

Miches

OK, first quick fix:

bool PrinterJob::Execute0(bool dodlg)
{
	pdlg = new Win32PrintDlg_;
	PRINTDLG& dlg = *pdlg;
	dlg.Flags = PD_DISABLEPRINTTOFILE|PD_NOSELECTION|PD_RETURNDC|PD_HIDEPRINTTOFILE;
	dlg.nFromPage = current;
	dlg.nToPage = current;
	dlg.nMinPage = from;
	dlg.nMaxPage = to;
	if(from != to)
		dlg.Flags |= PD_ALLPAGES;
	dlg.hwndOwner = GetActiveWindow();
	dlg.Flags |= PD_RETURNDEFAULT;
	if(!PrintDlg(&dlg)) return false;
	if(dlg.hDevMode) {
		DEVMODE *pDevMode = (DEVMODE*)::GlobalLock(dlg.hDevMode);
		pDevMode->dmOrientation = landscape ? DMORIENT_LANDSCAPE : DMORIENT_PORTRAIT;
		::GlobalUnlock(dlg.hDevMode);
	}
	bool b = true;
	if(dodlg) {
		DeleteDC(dlg.hDC);
		dlg.Flags &= ~PD_RETURNDEFAULT;
		b = PrintDlg(&dlg);
	}
	if(b) {
		draw = new PrintDraw(dlg.hDC, Nvl(name, Ctrl::GetAppName()));
		page.Clear();
		if(!(dlg.Flags & PD_PAGENUMS)) {
			dlg.nFromPage = dlg.nMinPage;
			dlg.nToPage = dlg.nMaxPage;
		}
		for(int c = 0; c < ((dlg.Flags & PD_COLLATE) ? dlg.nCopies : 1); c++)
			for(int i = dlg.nFromPage - 1; i <= dlg.nToPage - 1; i++)
				for(int c = 0; c < ((dlg.Flags & PD_COLLATE) ? 1 : dlg.nCopies); c++)
					page.Add(i);
		return true;
	}
	return false;
}

Unfortunately, this still does not solve the problem with landscape mode. Looks like calling CreateDC directly is the only option to achieve required operation...

OK this seem to work fine for all cases:

bool PrinterJob::Execute0(bool dodlg)
{
	pdlg = new Win32PrintDlg_;
	PRINTDLG& dlg = *pdlg;
	dlg.Flags = PD_DISABLEPRINTTOFILE|PD_NOSELECTION|PD_HIDEPRINTTOFILE|PD_RETURNDEFAULT;
	dlg.nFromPage = current;
	dlg.nToPage = current;
	dlg.nMinPage = from;
	dlg.nMaxPage = to;
	if(from != to)
		dlg.Flags |= PD_ALLPAGES;
	dlg.hwndOwner = GetActiveWindow();
	dlg.Flags |= PD_RETURNDEFAULT;
	if(!PrintDlg(&dlg)) return false;
	if(dlg.hDevMode) {
		DEVMODE *pDevMode = (DEVMODE*)::GlobalLock(dlg.hDevMode);
		pDevMode->dmOrientation = landscape ? DMORIENT_LANDSCAPE : DMORIENT_PORTRAIT;
		::GlobalUnlock(dlg.hDevMode);
	}
	HDC hdc;
	if(dodlg) {
		dlg.Flags = PD_DISABLEPRINTTOFILE|PD_NOSELECTION|PD_HIDEPRINTTOFILE|PD_RETURNDC;
		if(!PrintDlg(&dlg)) return false;
		hdc = dlg.hDC;
	}
	else {
		DEVNAMES *p = (DEVNAMES *)::GlobalLock(dlg.hDevNames);
		String driver = (const char *)p + p->wDriverOffset;
		String device = (const char *)p + p->wDeviceOffset;
		if(dlg.hDevMode) {
			DEVMODE *pDevMode = (DEVMODE*)::GlobalLock(dlg.hDevMode);
			hdc = CreateDC(driver, device, NULL, pDevMode);
			::GlobalUnlock(dlg.hDevMode);
		}
		else
			hdc = CreateDC(driver, device, NULL, NULL);
	}
	if(dlg.hDevMode)
		::GlobalFree(dlg.hDevMode);
	if(dlg.hDevNames)
		::GlobalFree(dlg.hDevNames);
	if(hdc) {
		draw = new PrintDraw(hdc, Nvl(name, Ctrl::GetAppName()));
		page.Clear();
		if(!(dlg.Flags & PD_PAGENUMS)) {
			dlg.nFromPage = dlg.nMinPage;
			dlg.nToPage = dlg.nMaxPage;
		}
		for(int c = 0; c < ((dlg.Flags & PD_COLLATE) ? dlg.nCopies : 1); c++)
			for(int i = dlg.nFromPage - 1; i <= dlg.nToPage - 1; i++)
				for(int c = 0; c < ((dlg.Flags & PD_COLLATE) ? 1 : dlg.nCopies); c++)
					page.Add(i);
		return true;
	}
	return false;
}

testcase (puttin' that to reference):

#include <CtrlLib/CtrlLib.h>

GUI_APP_MAIN
{
	PrinterJob pj;
	if(PromptYesNo("Landscape?"))
		pj.Landscape();
	if(!PromptYesNo("Use default printer?"))
		pj.Execute();
	Draw& w = pj;
	w.StartPage();
	w.DrawText(0, 0, "Hello world!", Roman(100));
	w.EndPage();
}
