- PSST -- PostScript from ST files
-
- Revision 1.1
-
-
- Summary
-
-
- This program will take several types of ST file and will produce
- an output that can be printed on one of several models of laser
- printer, giving clearer and more attractive prints than are
- available on impact printers.
-
- The program produces files written in PostScript(TM), a popular
- Page Description Language. The file is, in effect, a program that
- is executed by the printer. PostScript is implemented on several
- laser printers; the flagship is the Apple LaserWriter(TM), but
- there are several others. If your laser printer doesn't support
- PostScript, it can't print PSST output.
-
-
- Printing Files
-
-
- Nobody expects you to have an expensive PostScript laser printer
- attached to the serial port of your ST. So the program only
- produces the PostScript; it's then up to you to transfer the
- output file to another computer and send it to the printer. Maybe
- you have an employer who has these things scattered around, or
- maybe you have a friend with an Apple M**i**o*h desktop publishing
- shop. In any case, these two steps are obviously dependent on your
- local conditions. I work at Prime Computer; I transfer the files
- to a Prime host using Kermit, and spool the files on a LaserWriter
- which is attached via the printer's RS232 serial port.
-
- Note that all PostScript files produced by the program contain
- only the 95 ASCII graphics and newline. Furthermore no line is
- more than 80 characters long. This should ensure the file will
- travel through any communications medium unscathed.
-
- Each output file is self-contained. The program does not expect
- any definitions to have been previously loaded into the printer.
- This may change at future revisions.
-
-
- How to Use
-
-
- PSST uses standard GEM interactions. The basic operation is
- triggered by the "Open..." selection under the "File" menu. This
- prompts you to select an input file and an output file. The
- program then figures out what kind of animal the input file is,
- and produces an output file correspondingly.
-
- For example, if the input looks like a Neochrome file, the
- PostScript file will print the Neochrome picture.
-
- If you want to override the program's attempts to guess, use the
- "File type..." selection under the "File" menu to force a
- particular type. You might want to do this if, for example, you
- have a Neochrome file that has no .NEO suffix. But PSST will
- still check the file for internal consistency.
-
- Any file can be printed in a hexadecimal dump. Also, any file
- can be printed as an ASCII listing, but if the file doesn't look
- much like an ASCII file, the program will ask you to verify your
- intentions.
-
- Use the "Options..." menu to tailor different aspects of the
- output in its main modes: Graphic, Ascii/Hex and WP.
-
-
- Example
-
-
- For example, suppose you want to produce a print of your Degas
- Elite picture SHUTTLE.PC1, aligned vertically so as to occupy most
- of the page.
-
- 1. Load PSST, and under "Options", "Graphics..." select Landscape.
-
- 2. Under "File", "Open..." select SHUTTLE.PC1, and accept the
- program's suggestion of SHUTTLE.PS as output.
-
- 3. If you are running in low resolution, the program will display
- the picture and fade it to monochrome so that you can see how
- it will look on the monochrome printer.
-
- 4. SHUTTLE.PS will then be written.
-
- 5. Use Kermit to transfer it to the host of your choice, ask
- around for how to print a PostScript file, print it and be
- amazed!

- Issues
-
-
- Here are some notes about the current state of PSST.
-
- - Revision 1.1 (August 1987) supports only Graphic (Degas and
- Neochrome), Ascii and Hex Dump. The next on the agenda is 1ST
- Word (REAL bold and italic, and maybe REAL proportional
- spacing).
-
- - I know of no printer that currently supports the PostScript
- color model. PSST only produces monochrome images. Colors are
- converted to shades of gray using the NTSC transformations.
-
- - In ASCII mode, characters from the extended character set are
- not printed.
-
- - Some inactive entries in the File Type menu aren't dimmed.
