I apologize if this is a FAQ, but is there some way I can control the line weight when I print Mac window contents to a LaserWriter? I need to print very complex electrical drawings, but the output is too dense. Please respond either directly to me or to this group.

Use a PrGeneral call (see Inside Macintosh Vol. V) to find out what resolutions the printer supports, and another one to set the imaging resolution you are going to use. In the case of a (Postscript) LaserWriter, you will see a wide range of acceptable resolutions; use 300 for simplicity -- or if you think the picture might someday be printed on a 1200 dpi printer, specify that, or some larger number; Postscript and the LaserWriter driver will take care of you. For other printers you will see a set of resolution values; pick the one you like (presumably the highest). It's good practice to make your code printer-independent, so you should allow for these cases; who knows, you might need to print a draft on an ImageWriter some day. Having set the imaging resolution, just scale each object that you draw by the ratio of that resolution to 72 x 72. David Casseres Exclaimer: Hey!

There are two ways that you can do this: 1) Work at the printer's resolution instead of the screen resoultion. See IM-V, pg 413 for a discussion of PrGeneral and GetReslData and SetResl. This will allow you to place all your objects exactly where you want on the page. Disadvantage is that you have to scale your drawing yourself. 2) Use the picSetLineWidth picture comment. This is described vaguely in Tech Note #91, and then much more completely in TN #175. This will allow you to "thin" all the lines in your drawing by some factor. Disadvantage is that it only thins lines and frames. Hope this helps, Marshall Clow Hewlett Packard Color Imaging Internet: marshall@sdd.hp.com AppleLink: HP.Marshall
