MacPaint represents used, there are several tricks that we had to figure a drawing by bit images, and thus its resolution out to get everything working together smoothly. is limited to the resolution of the Mac screen. We're describing the tricks here, so that others can MacDraw represents a drawing by a list of the benefit from our experience. We will assume that objects involved (square, oval, line, etc.) and their the reader is familiar with MacDraw and the general location on the page. Its resolution is determined by operating principles of the IBM AT and Macintosh. the resolution of the output device. Generating PostScript Files MacDraw is capable of generating PostScript Prepare your MacDraw disk by installing the files which can be used to generate high resolution LaserWriter icon in the system. You do not need (300 dpi) images on the Apple LaserWriter and other to have the Laserprep file on this disk, but you will PostScript printers. Textset has developed a DVI to need that file later. PostScript translator, DVILASER/PS, that allows Start PllacDraw and create an illustration in the DVI files to be printed on a PostScript printer. It top 3 inches of the page. This is basically the area seemed to us that it would be useful to be able to shown on the Macintosh screen. The TEX macro merge the graphics images generated by MacDraw defined below expects to find the hIacDraw drawing with the text output generated by In this note m. in this location. Of course it can be rewritten to we describe how we were able to accomplish this. find it elsewhere or to scale or rotate the hIacDraw An Overview drawing before merging it into the document, Once the system is in place it is quite easy to use. but we leave that up to you. First you run MacDraw on the Mac and create your When you have completed the drawing, it drawings. Then you create the PostScript files on is a good idea to save it in case something goes the Mac, and transfer them to the computer on wrong. Once you have done that you can create which you will be running DVILASER/PS. (We did the PostScript file which describes the drawing. To most of our work on an IBM AT, but DVILASER/PS accomplish this you must begin by making sure also runs on a number of other operating systems you have selected the LaserWriter printer using the "Select printer" desk accessory. Then open Editor's Note: this article was originally printed on MacDraw and choose the "Print" option. l+-hen the an Apple LaserWriter using the Laserwriter's Times LaserWriter menu box comes up, you hold down the Roman fonts, with the illustration in Figure 2 inserted by the DVILASERiPS program.

The Mac will then create a file that contains parity, etc. We used 9600 bpi and no parity. Now the PostScript commands that it would normally set the Mac to "Be a server" and move to the AT send directly to your LaserWriter. It stores these and type "get filename" where filename is the name commands in a text file called "Postscript." of the PostScript file on the %lac that you want to There seems to be no way to get it to use a more transfer. If all goes well, the file will be transferred informative name. Of course, you can use the Finder over. Again, there are other procedures that you to rename the file to something more meaningful. can use, but we found putting the Mac in the server Since you are going to transfer this file to the mode and using "get" was the quickest and easiest PC, it is a good idea to give it a legal MS-DOS for us. If you have your Postscript files on a Mac name. However, to rename the file you have to exit drive other than the default drive. you can use the MacDraw. This is not a great problem if you are -send file" menu to change the default drive before only converting a few files, but if you are converting using "get." many files, it can take a lot of time. We used a Preparing the LaserWriter public domain desk accessory called .'Rename" which Now you are almost ready to print your document. allowed us to rename the PostScript file from within But first you have to prepare the LaserWriter to MacDraw. There are other desk accessories available accept the SIacDraw document. Remember the file that will also rename files. but we stuck with the first LaserPrep that comes with your LaserWriter? This one we found that worked. file consists of a number of Postscript procedures The properly named file can then be that are used by MacDraw. You have to send this incorporated, as is, into your TEX document via file to the LaserWriter before it can understand the the \PrintMacDraw macro defined below.

A copy of this We used an IBM AT, but similar procedures should file is included with DVILASER/PS. work for other computers. If not, you can still create one for yourself, but We used KERMIT to transfer the PostScript file it will take more work. Here is how you do it. First, from the Mac to the AT. There are other systems get hold of the Shareware editor FEDIT, created by available that should work equally well, but we'll John Mitchell.
