First make sure a LaserWriter driver is in your System Folder.
It doesn't really matter which one although LaserWriter driver
8.3.4 is the best. This driver is available from
and works with System 6.0.5 and later. If you're using the System 6
driver, you'll need a Laser Prep file in your System Folder as well as
the LaserWriter driver and will also need to turn off background
printing. Once you've verified that there is indeed a LaserWriter
driver in the System Folder, select LaserWriter in the Chooser.
A dialog box will probably pop up informing you that the LaserWriter
requires Appletalk and asking if you want to turn Appletalk
on. Whether you have AppleTalk or not click OK. Then select
Page Setup... from the File menu to format your document
for the LaserWriter. Next select Print... from the File menu.
If you're using LaserWriter driver 7.0 or later, the Print
dialog box that appears will have a radio button for Destination
near the bottom. Click PostScript File. The Print button at the
top should change to a Save button. Click it and you'll get a
standard file dialog asking you what to name and where to save
the PostScript file.
If you're using LaserWriter driver 6.0.x or 5.2, the procedure
is more complicated. When the Print dialog box pops up, position
the cursor over the Print button and hold the mouse button down and
keep it down like you're going to click and drag. Then, with your
other hand, press and hold the K key. If you'll eventually print
the file on a non- Apple PostScript printer, especially one not
designed with the Macintosh in mind, also hold down the Command
key. Using Command-K instead of plain K includes some Mac specific
information non-Apple-oriented PostScript printers need to know
about. Now let the mouse button up. When you see a message box
that says "Creating PostScript file," take your finger off the
After you've gotten the message "Creating PostScript file" you
should find a file called PostScript0 in the same folder as the
application you were printing from. This is the file you just
printed. Rename it before you forget what it is. If you print to
disk (what this whole process is officially called) more than once,
the second file will be called PostScript1, the third PostScript2,
and so on. It really is much easier to use the System 7
