HI,
I want to print an BITMAP* on default system printer in WinXP + DevCPP/MinGW/GCC and ofcourse Allegro.
How can I do it?
Perhaps using geting printer Canvans and drawing onto them method.
I had some small example program but it had unresolved references while linking... perhaps a complete C/C++ source + what libraties/options use (and where to get them from)?

How can I use shellexecute to alternatively print a document by saving it into a .bmp first?

Is it possible to get metrics of printer page / etc - to have image fit-to-screen? How to get/set the DPI of image (and set paper type to A4 page)?

Thanks in advice! (Btw I need answer quickly, so I would be greatefull even for any clue).

You could convert the BITMAP* to an HBITMAP using the Allegro function. I assume printing an HBITMAP is fairly simple, though I haven't had occasion to try it ...

No, it is rather tediously. You need to setup a lot of things. Even with MFC is a pain in the a**. I suggest you to save the bitmap on hard disk, and let the user print it later.

if only that "Print Screen" button did what it was supposed to.
and can anyone tell my what a Scroll Lock key does ?
or why we still have a caps lock key so large ?

Surely couldn't you just save the screen as a bitmap and then call the system command to print a bitmap.

Eg in windows:-
"C:\WINNT\system32\mspaint.exe" /p "%1"

I assume you're just trolling as usual, but anyway...
Scroll Lock - surprise - locks scrolling. Very handy for console work where you only have a screen's worth of buffer.
The caps lock key is big because you want to keep a straight outer line with the keys and at the same time indent the second alphabetic key row.

My application is used to encode encrypted images after giving a password, and allows to view image. It also should print the image.

I know that there are many ways to steal image anyway - printscreen for example, or scanning printed image but I want to make it as hard as possible, so saving a .bmp to disc and running paint on it is a bad idea...
