- EHANDLER.PS The error handler program
- Copyright (c) 1984, 1985, 1986
- Adobe Systems Incorporated.
-
- PSINFO.PS A short program that prints a very
- small amount of printer information
- and acknowledges that the error
- handler has been downloaded.
-
- PSSEND1.BAT A batch file to copy both PS files
- to a printer on LPT1.
-
- PSSEND2.BAT The same batch file set up for LPT2.
-
- PSERROR.ICO A Windows icon file.
-
- -------------------------------------------------------------
-
- These files should all reside in the same directory.
-
- Either one of the .PS files may be copied directly to the
- printer from the DOS prompt (COPY EHANDLER.PS LPT1) or the
- batch file may used to send both of them. If your printer is
- connected to LPT1 then you should use PSSEND1.BAT. If your
- printer is on LPT2 then you should use PSSEND2.BAT. If you
- are using another port you will need to edit the batch file
- (e.g. remark out the reference to LPT1 and enable the line
- that corresponds to the correct port). You may use any ASCII
- text editor such as EDIT or NOTEPAD.
-
- To set up an icon on the Windows desktop, the following steps
- should be taken:
-
- >Select the group where the icon will reside.
- >Open the File menu and select 'New'.
- >Select 'Program item' and hit 'Ok'.
- >Hit the 'Browse' button and select the directory
- where the files are located.
- >Select the PSSEND1.BAT file and hit 'Ok'.
- >Hit the 'Change icon' button and then the 'Browse' button.
- >Select the directory where the files reside.
- >Select the PSERROR.ICO file and hit 'Ok'.
- >Hit 'Ok' again.
- >Type in a name (Error Handler) in the Description field
- and hit 'Ok'.

- The most common error encountered when printing graphics
- files is the LIMITCHECK error. This type of error can arise
- if a PostScript limitation has been exceeded. This can be
- caused by commands such as EOFILL, EOCLIP, STROKE, FILL and
- CURVETO. These operators are all sensitive to the resolution
- of the PostScript device to some extent. The end result is
- usually an object(s) that are too complex, most often a curve
- with an excess of 300-400 nodes. Although PostScript is a
- very universal language, these errors will sometimes not
- become apparent until the file is printed on a high-end
- imagesetter. There will typically be many more line segments
- when flattening a path on a high resolution device than on a
- low resolution (300-600 dpi) device, hence the susceptibility
- to complexity problems. The frequency of this type of error
- will be substantially lower on Level 2 devices due to dynamic
- stack and Virtual Memory allocation.
