I'm trying to print documents containing images, pasted fom clipboard. My problem is, that the pictures get messy on printer or in a ps file, captured by printer driver.
PDF export is OK and printing the exported PDF from Adobe reader is OK as well.
Could somebody check if it is a general problem/bug?

Strange...
It is working well with color printer driver (ps).
Testing the output postscript captured on driver (saved to file) seems to be good with color drivers, but messy with black and white drivers.

Any idea?

Sorry, one that I have missed....

Will test ASAP... Have you checked how printing works from e.g. WordPad?

What exactly means "messy"?

It is something more serious, I would start looking at DrawImageOp; there is "band compression" code

	if((cx > 2000 || cy > 2000) && IsNull(color)) {


for starters, I would make this false (e.g. ".... && false") and see what happens.

Just for the recored, printing works here....

Note: The purpose of this code is to "compress" unicolor areas by painting them using DrawRect.

This is the original picture:
index.php?t=getfile&id=595&private=0

I used ghostview to check the captured postscript files and created screenshots of ghostview windows:

Color printing (HP Color LaserJet 8550-PS driver):
index.php?t=getfile&id=593&private=0
Color, stretched to smaller size in Uword:
index.php?t=getfile&id=594&private=0

B&W printing(HP LaserJet IIIP PostScript Plus driver):
index.php?t=getfile&id=591&private=0
B&W, stretched to smaller size in Uword:
index.php?t=getfile&id=592&private=0

I tested WordPad as well:

B&W:
index.php?t=getfile&id=596&private=0

B&W stretched:
index.php?t=getfile&id=597&private=0

I have tested with:
if(false)

The result with color printer is quite good:
index.php?t=getfile&id=598&private=0

Bit with B&W printer, I got a solid line only:
index.php?t=getfile&id=599&private=0

Well, at least it seems to be related...

Can you post your UWord file as well (so that I can test with the same)?

Prints without an issue for me.... (LaserJet 6L).

Actually, looks very much like printer driver problem - but I understand such explanation is not very helpful...

I will move .qtf file to some more exposed forum place and ask others for tests.

Interesting...
I tested with "Brother HL-8PS" driver, the result is the same as with HP.
But with "Lexmark Optra W810 PS" driver, the result is almost perfect. If I scale the image to a smaller size, the printout is perfect.

Thanks Mirek!

I saw the posts in the other topic.
Maybe the problem is, that older printer drivers in Windows XP doesn't support well the whole printing API of Windows.

I will suggest to my clients to use a newer printer or at least a newer driver.

BTW, I think it is somehow related to printers being PS...

If I remember well, HP printers can run in both modes (Postscript and PCL) - maybe switching to PCL driver could be interesting...

Using PCL, printouts are bad also. I started to use postcript to test if the printer is bad or not. And it is easy to see the results with a PS viewer without printing to paper.
