Print Window to Printer

Reinhard had a recent problem where he had a window with text and graphics that he wanted to print out.

He had several problems. Part were the flags he used in defining his window. When that was corrected  he was left with one major problem.

Although he had created his window proportional to an 8.5 x 11 page when it was printed it only was printed (properly scaled) on about 1/4 of a page.
He used the IWB PRINTWINDOW command.
Apparently what happened is that it scaled the SCREEN to 8.5 x 11 and then printed his window to that scale.
I couldn't find a way to get around that with the PRINTWINDOW command directly.

So, I took some code I used in the IWBasic IDE Print Preview,  stripped it down and modified and come up with a subroutine that you can use to print any window to the printer.

If you scale the size of window to 8.5 x 11 then when you print it should fit pretty close.  You can always fudge the scale if necessary.

You'll have to use $include "windowssdk.inc"

LarryMc,

The window that you want to print can be no bigger than the screen resolution, right?  Is it possible to make a hidden window bigger than the screen, print text and graphics on it and then use your printwindow2printer sub?

Clint

You can make a hidden window any size you want.
But you still have to scale it to print on the paper

I did that, but I made it big to get better resolution.  That put some of the HIDDEN window out side of the screen, and couldn't be printed on.  My screen is 1366 x 768 and it would print nothing on the window over 768, which made for a very low res printout.

It looks like the window should be made persistant no matter how big it is, like 1600 x 2000 pixels.  Then when it scales to print it would have good resolution.

Hope this makes sense.  This is my chemo week and am in a little bit of a brain fog.

This should show what I'm talking about.  You need windowssdk.inc at the top like always, then printer.inc. Place it in the same directory as MyPrintertest.iwb.  It will only print part of the page even though it is scaled to 8.5 x 11.  If you make it so the height is no bigger than the height of the screen, it will work but al least my printer looks like a low res printout.

Larry,

Could you give me a heads-up on how you implement or call this code in a program, please?

the posted example by Clint just before yours has a working example.

Got it now, Larry - thank you. Will give it a whirl

You could check out this thread on the printer routines I worked on last year.  There is a lot that could probably be improved on.  The disadvantage is that you need to set up seperate routines to print/draw to your window and to print/draw to your printer.  The advantage is you get high resolution printouts.
