Re: [JAVA2D] Black and White printing
Perhaps you could create a BufferedImage.TYPE_BYTE_BINARY with a 2 color IndexColorModel and have all the printing go into there. Then all rendering will have to be one of those two colours which I assume you would select as BW. The drawbacks to this are that to get printer resolution graphics (something you also were seeing problems with already) that BufferedImage will need to be big and you will have to scale it appropriately and the resulting spool file will also be huge. Another drawback is that it may not look very pretty. In any case I don't see a way to do this via the printing APIs. -phil. [EMAIL PROTECTED] wrote: Phil, I'm still puzzled.

The problem with monochrome printing is the user has a yellow line drawn and wants to print it on a black and white printer. If I use grayscale it comes out as a faint line on the paper. When it copys this or puts it on a viewfoil it is very faint and noone can read it. So the need for Black and White.

[JAVA2D] Black and White printing
I only know about printing from the tutorial and using it as a service. I want to add to the print menu : Black and White to the picks already there of Monochrome and Color. What is best way to do this.

Re: [JAVA2D] Black and White printing
Do you mean you want to update the list of choices the user sees for some reason? The dialog is not customisable in this way so you'd have to write your own dialog. Also I wonder how you expect to communicate this intent to the printing API and ultimately to the printer driver For example, on windows you can tell the printer driver to use either Monochrome or Color (assuming its color capable) via a GDI DEVMODE setting. There's no additional BW setting. So if for some reason your purpose is to have a purely bilevel output rather than printing in shades of grey via half-toning or the like, then I don't see how to do this except to control the actual colors that are used and limit them to black and white So monochrome *IS* BW - ie use only black ink and the printer just dithers the black ink to achieve the perception of grey levels (unless you have a rare printer which has grey inks) -phil.

Re: [JAVA2D] Black and White printing
Yes I understand that I need to display a new dialog. Black and white is not the same as monchrome. With monochrome you get shades of gray. I want the background to be white and all drawings to be black.

Re: [JAVA2D] Black and White printing
I want the background to be white and all drawings to be black So you need to proceed as I advised but the new dialog seems like a lot of work for little gain. We can't add it in our dialog as we can't control the colours you use. -phil. Yes I understand that I need to display a new dialog. Black and white is not the same as monchrome.
