- LASER PREP INSTRUCTIONS
-
- For Users of the Apple Macintosh(tm) and PostScript(tm)
-
- June, 1985
-
-
-
- DISCLAIMER and TERMS
-
-
-
- The text-only version of the file "LaserPrep" (also known as the "Apple
- header") is provided in cooperation with Apple Computer, under the
- following terms:
-
-
-
- 1. The header text is provided strictly as a courtesy to our mutual
- customers who have requested it. This text file is not a product, and it is
- provided strictly "as is". *** Neither Apple Computer nor Adobe Systems
- provides any support for the use of this file. *** Apple Computer and
- Adobe Systems disclaim any warranty or liability obligation whatsoever
- regarding its use. *** The user must be aware that Apple may change the
- contents of the LaserPrep file at any time, without notice, and without
- providing updates.
-
-
-
- 2. The header file is the property of Apple Computer, and all rights are
- reserved. It may not be sold, resold, or licensed.
-
-
-
- 3. A copy of this disclaimer and instruction sheet should accompany any
- copy of the header file.
-
-
-
-
-
- INSTRUCTIONS FOR USE
-
-
-
- The text form of the LaserPrep file is useful when one wishes to upload
- MacDraw documents or other formatted Macintosh documents to another
- computer, and print them from that host to a LaserWriter. It can also be
- used to print from a Macintosh to a PostScript printer over an RS232
- connection. In many cases these goals can be accomplished by following
- the instructions provided in the next pages.
-
-
-
- Two versions of the LaserPrep file are included on this disk. The one made
- available to Adobe is titled LaserText. Another version, recently placed on
- a nationwide computer network, is titled LaserText (Reid). They are
- substantially the same. Hackers may benefit from the variances in
- embedded commentary.
-
-
-
- In order to convert LaserPrep into a downloadable text file, certain lines
- of PostScript code were commented out with "%" symbols. We recommend
- that you not change any of these comment lines unless you are very
- familiar with PostScript.
-
-
-
- We hope the text form of the LaserPrep file, and the following
- instructions, will be of assistance to you in using the Macintosh and
- PostScript. Please remember that neither Adobe nor Apple provides any
- support for the use of this text file.
-
-
-
- Sincerely,
-
- ADOBE SYSTEMS INCORPORATED

- INSTRUCTIONS FOR USE (CONT.)
-
-
-
- *** IN BRIEF ***
-
-
-
- I. Spool the PostScript output of the Macintosh application into a text
- file.
-
- II. Prepend LaserText to your PostScript file.
-
- III. Send the header+data text file to the PostScript printer.
-
-
-
- There are several important details to be observed. Please read the
- following instructions at least once.
-
-
-
-
-
- *** IN FULL ***
-
-
-
- I. "Spool" the PostScript output of the Macintosh application into a text
- file by using "Command-F" as documented below. This file may be uploaded
- to another computer if desired. It can also be edited to add special
- PostScript effects.
-
-
-
- The Apple header provided here does not contain code for the
- bit-smoothing provided as an option with some applications, such as
- MacDraw and MacWrite. Do not use the "smoothing" option when spooling
- your PostScript files, or you will crash the job when you attempt to print
- it out. Some versions of MacPaint automatically employ smoothing. Such
- files must be printed through MacDraw or MacWrite, without smoothing.
-
-
-
- The following instructions are taken from Inside LaserWriter, Appendix F,
- Section: "Instructions for Spooling, Editing and Downloading a PostScript
- file from a Macintosh application".
-
-
-
- When a Macintosh application is told to print a document on the
- LaserWriter, the PostScript output that is generated can be spooled
- (redirected to a disk file) instead of being sent to the printer:
-
-
-
- 1. Select "Print" from the application's File menu in the usual way. (The
- system disk must already have "LaserWriter" installed, although the Mac
- doesn't have to be physically connected to a LaserWriter.)
-
-
-
- 2. When the Print dialog box appears, click "OK" in the usual way.
-
-
-
- 3. Immediately press the Control and F keys simultaneously and hold
- them down until the message "creating PostScript file" appears on the top
- of the screen.
-
-
-
- 4. When spooling is done, quit from the application. A file labelled
- "PostScript" should be on the disk. If there was a previous file named
- "PostScript" on the disk, it will have been destroyed.
-
-
-
- 5. Rename the file as something other than "PostScript" if you want to
- keep it so it is not destroyed the next time you spool a PostScript file.
-
-
-
-
-
-
-
-
-
-
-
- II. Prepend the contents of the Apple header (LaserText) to your
- PostScript data file. If you are combining several files, the header needs
- only to be included once at the beginning of the concatenation.
-
-
-
- If you use a Macintosh or PC word processor to concatenate the header file
- with the PostScript file, be sure to save the result as "text only".
-
-
-
- Most mainframe word processors produce ASCII-only files automatically.
-
-
-
-
-
- III. Now send the header+data text file through a standard RS232 port to
- any PostScript printer.
-
-
-
- On mainframes, appropriate serial drivers are usually available. If you are
- using a system with Adobe's TranScript(tm) software, the lpr command
- will work.
-
-
-
- On a Macintosh you may use MacTerminal or other communication
- programs.
-
-
-
- On PC's, you may use terminal emulator programs, communication
- programs, or redirected type or print commands.
-
-
-
- The most useful RS232 settings are usually 9600 baud, 8 bits, no parity,
- no stop bits; the LaserWriter switch should be in the second postion,
- "9600". The LaserWriter uses XON/XOFF protocol and expects to be able to
- send asynchronous error messages. If your hardware or software does not
- support XON/XOFF and bidirectional communication, you may still be able
- to communicate satisfactorily for short, error-free files.
-
-
-
- A complete description of how to connect to the LaserWriter serial ports
- is contained in the Apple LaserWriter Advanced User's Supplement. This
- supplement is distributed with Inside LaserWriter from Apple, and with
- the PostScript Language Manual from Adobe.
-
-
-
- If you are using both the Macintosh and LaserWriter in an AppleTalk
- environment, you have an alternative to using the serial port and
- MacTerminal. You may leave the LaserWriter in "AppleTalk" mode, and use
- the program Downloader to send text-only files over AppleTalk. The
- Downloader program is distributed with Inside LaserWriter from Apple.
