How to print a Windows Bitmap file ?

I'd like to send Windows Bitmap files to a printer.
Would it be possible to perform that task using PCL commands ?  Otherwise how to do that using Win32 APIs ?

Thanks

1. Sorry, I don't have any knowledge about PCL.
2. I.e. MSDN article ID: Q139652 'Print a document'

again: It's strongly recommended to not use any hardware dependant printing. There's no advantage in using PCL. This would restrict your program to run only with printers which support PCL. Using windows GDI functions (based on device independant device context) is even simple and more flexible.

Hi edsont,

using PCL commands wouldn't be a good way coz it makes your program hardware dependant...

Better way: simply create a printer device context and a memory device context, load the bitmap, select it into the memory device context and from there blit it to the printer device context using StretchBlt() (or BitBlt() if you don't need scaling).

See help for PrintDlg, CreateCompatibleDC, SelectObject and StretchBlt...

you're welcome to ask if you have further question...

hope that helps,

Zoppo,


Alternatively would you happen to know if PCL commands work in that context ?


Thanks

If you need to use PCL commands (which is not recommended), you'll have to send your data directly (as raw data) to the printer without using the windows printer drivers. See MSDN article ID: Q138594 for how to do this.

Zoppo,

Two more questions:

1. Would you know which PCL commands could be used ?
2. Does it exist any MSDN sample using printer device context way but without MFC classes ?

Thanks

My problem is that I already have a software that uses PCL commands to print. People asked for bitmap files printing but I wouldn't like to change it a lot.

Anyway I'll take atention to your suggestions.

Thanks

The writePrinter API function works with a printer handler. Tha printer handler can be obteined from an OpenPrinter API Function.

I think that if you create an array of bytes of your bitmaps, maybe you can print it using the writeprinter function.

I have the same problem, and the hard way is to send a Array of bytes for a BitMap through the writeprinter function

GetObject Picture1.Image, Len(PicInfo), PicInfo
'reallocate storage space
ReDim PicBits(1 To PicInfo.bmWidth * PicInfo.bmHeight * 3) As Byte
'Copy the bitmapbits to the array
GetBitmapBits Picture1.Image, UBound(PicBits), PicBits(1)
'Invert the bits
For Cnt = 1 To UBound(PicBits)
PicBits(Cnt) = 255 - PicBits(Cnt)
Next Cnt
'Set the bits back to the picture
SetBitmapBits Picture1.Image, UBound(PicBits), PicBits(1)
