Dear All,
I have created a set of commands that can output text and graphics to printing devices. I am releasing a beta version to help me to identify any issues that may arise. This libray is not available for general release yet. Please visit my web site to get the latest download.

I am not going to able to reply to any queries though until tuesday morning at the earliest. The documentation is all online at the moment. If you have any critisms ( especially ) or suggestions, please could you email me trial@zogtrog.plus.com. This would be appreciated as these mail messages get echoed all around the world
and stored forever.

Here are some more details of what my plug-in is capable of

Dark ink can print text, bitmaps and images, lines,

rectangles and ellipses. You can output pretty much anything you like to the printer. I have created a BETA trial release as it is

impossible for me to test it againt all the computer/ printer combinations that exist. I have tested it with an epson c64 printer

and microsofts XPS document writer under windows 64 bit version of windows. The plug-in is fully documented and can be downloaded

from my web site.

There has been a problem with some missing files.
I have compiled my project differently, so hopefully this should elimate the need for any external files. I have updated my files BETA version 1.0.1.1

You can get the latest version from

This looks pretty useful for applications.

The
Quote: "GET PRINTER PAGE HEIGHT - returns page height
GET PRINTER PAGE WIDTH - gets the page width"

returns the sizes in pixels right?

Is there also a way to change the DPI (if this is possible)?

Yeh at the moment it just returns pixels
I was thinking about adding some conversion functions anyway. I will probably implement some functions to allow scaling between pixels, inches, and cms, mms etc.
I am not sure you can change the number of dots per inch your printer prints at, is that what you mean ?
You can change the print quality which alters the DPI you are using the SETUP PRINTER DIALOG FUNCTION although I guess it might be handy to be able to store and load settings, so they don't have to be re-configured every time you run your app.

Well, not necessarely the DPI of the printer itself.

I meant for the document. Would you have to scale down/up your images to the document width, or would it be possible to actually set the page width and height in pixels?

I'm not that much of a genius when it comes to printers, so it might not even be possible. It would just save alot of time...

The number of pixels is generally fixed for a given paper size for your printer. What governs the width of your image is the number of pixels multipled by the width of 1 pixel on the device you are drawing to. The height is governed in a similar fashion. Pixels are not necessarily square, they can be retangular to.
In short you have to scale your images if you want them to appear to be a certain size. Scaling small images to large images can lead to pixelation. Like I said in my last post, I need to add functions to my library which will allow you to get dimensions in inches and millimeters. I am hoping to get round to doing this sometime next week.

Best Regards,
