You can receive a PostScript error when sending a file to a PostScript interpreter (for example, a printer, Acrobat Distiller). A PostScript error occurs when the PostScript interpreter can't read the file's PostScript code. An error can also occur if the file's PostScript code exceeds one or more of the limits in the PostScript page description language. If your PostScript interpreter appears to process data but then stops, a PostScript error could have occurred.
A PostScript error message includes a PostScript error type, which defines the type of error it is. It also includes an offending command, which usually indicates the specific part of the PostScript code that the interpreter couldn't read. The offending command usually indicates the command that caused the problem. Some PostScript errors point you right to the cause of the problem, and some get you looking in the right direction.
Example of a PostScript error:
%%[Error: ; OffendingCommand: ]%%
For example, the PostScript error %%[Error: dictfull; OffendingCommand: def ]%% contains the PostScript error type "dictfull" and the offending command "def." The error type indicates that the dictionary contains the maximum number of entries. The offending command is the last command the PostScript interpreter tried to process, "def," which defines a new word in the dictionary.
If you think a PostScript error has occurred, but it doesn't appear onscreen or in your printout, you can sometimes view or print the error message. Do one or more of the following:
Note: In Windows NT, you cannot configure a printer to print an error message.
Note: If PostScript Options isn't visible, double-click Document Options
After you identify a specific PostScript error message, you can begin troubleshooting the cause. To begin troubleshooting, locate the error type and offending command in the "PostScript Error Types" and the "PostScript Offending Commands" parts of this document. You can then try to repair the problem.
For example, you could receive the PostScript error, "%%[Error: limitcheck; OffendingCommand: image ]%%." Your first step is to locate "limitcheck" in the "PostScript Error Types" section. The "PostScript Error Types" section lists "limitcheck" under the heading "Exceeds printer's memory or PostScript language limit." The "PostScript Offending Command" lists "image" under the heading that indicates a problem with bitmap data. So, you have bitmap data that exceeds the printer's memory or PostScript language limit. The likeliest source of bitmap data is a graphic in your file. You can then check graphics in your file to see if one or more is causing the problem. If you find a likely culprit, you can delete the graphic, reimport it, save it in different format, or simplify it (for example, reduce its dpi). You can also try printing the file to a printer with more memory.
Some PostScript errors don't help you determine a likely cause. For example, you could receive the PostScript error "%%[Error: undefined; OffendingCommand: ]%%." The "PostScript Error Types" section lists "undefined" under the "Errors that indicate unintelligible PostScript code" heading. The "PostScript Offending Command" section lists "" under the heading that indicates a problem with any element or file. In this case, your file contains PostScript code the PostScript interpreter can't recognize. See the "Troubleshooting Possible Causes for the PostScript Error" section to continue troubleshooting.
Following are common error types, grouped by general cause.
The following error types indicate that something exceeds the PostScript interpreter's memory or a PostScript language limit:
The following error types indicate the file contains unintelligible PostScript code:
Following are common offending commands, grouped by general cause.
The following offending commands indicate a problem with specific text or a font element:
Note: For font-related errors, try changing the font-related settings in the device driver. For example, in the printer's properties (Windows), click Advanced, then, in the Graphics section, change the TrueType Font option to Download as Softfont.
The following offending commands indicate a problem with specific masks (for example, clipping paths):
The following offending commands indicate a problem with fills and lines, often in imported object-oriented, or vector, graphics (for example, EPS, PICT):
The following offending commands indicate a problem with bitmap data:
The following offending commands indicate a problem with any element or graphic:
Many PostScript error messages readily indicate the source of a problem. Troubleshoot a problem further if you receive a non-specific PostScript error message, or if a PostScript error occurred without a message. To troubleshoot a PostScript error, isolate when the problem occurs to determine if it is a system-level, application-specific, file-specific, or element-specific problem. After you isolate when the problem occurs, you can eliminate likely causes until you solve the problem.
Do you receive the error from more than one application? If the same problem occurs from more than one application, the cause is most likely a problem at the system level. Damaged fonts, damaged system files, damaged printer drivers, insufficient hard disk space, network problems, or hardware problems commonly cause system-level problems. If the problem occurs only from one application, see the "Isolating Application-Specific Problems" section.
Make sure that you use an up-to-date PostScript device driver (for example, printer driver). Or, use the version of the driver required by the application. You also need plenty of free hard disk space when sending a file to a PostScript interpreter, especially when you print a large file. Make sure that free hard disk space is defragmented.
If you print to an external PostScript device, secure loose connectors (for example, cables, switch boxes) by unplugging and replugging them. You can easily tell if a connection to an external device is severed altogether: The device doesn't receive any data, so nothing happens. But if a connection is loose, the symptoms of a problem can be unclear. The device receives small jobs only, or its driver appears only intermittently in the Chooser in Mac OS.
If you print to an older PostScript printer or one that uses a PostScript emulator (for example, a LaserMaster or LexMark printer), it possible it doesn't recognize newer PostScript code. Try printing the file to a printer or RIP that contains a more current version of Adobe-licensed PostScript.
Do you receive the error only from a single application, and in every file from that application? To determine if the application or a specific file causes the error, create a file with only a simple element, such as a rectangle. If the error doesn't occur with this test file, the application itself isn't causing the error, so you can move to the "Isolating File-Specific Problems" section. If this test file does cause the error, the application software could be damaged. Delete the application's preferences file, and then reinstall the application from the original installation disks.
Do you receive the error only with a specific file or files? If the error occurs only with a specific file, the file could have the wrong print settings selected for your PostScript interpreter. Or, it could be damaged or contain a problem element (for example, a damaged graphic). You can begin troubleshooting the file by using the same print settings as the settings of a file that doesn't cause an error.
To determine if the file itself is damaged, copy the file's contents into a new file. Save the new file using the Save As command, and then see if the error occurs with the new file. If the error doesn't occur, the original file is damaged. If the error does occur, run any built-in diagnostic routines your application offers.
Do you receive the error only with a specific page or elements on a page? After you rule out a damaged file as the cause, a damaged or incorrectly written element or font is likely causing the error. An element or combination of elements that requires more memory than is available could be causing the error. If the error occurs with a range of pages, look for common elements on those pages. If you can print all elements individually or in small groups, the combination of elements you print requires more memory than is available.
To isolate the element or elements that cause the problem, make a copy of the file. Then send groups of pages to the PostScript interpreter. If a group causes an error, print one page at a time from that group. Continue sending pages until you narrow down the problem page. You can then isolate the elements causing the problem by removing elements from each page. If you remove a page and the error doesn't recur, the elements you just removed cause the problem.
If an element that causes the problem is text or an element you created in the application, re-create the element. For text elements, you can also try using a different font (for example, reformat the text using a different type of font). If the error doesn't recur with a different font, the previous font is damaged. Reinstall it from the original media.
If the element causing the problem is an imported graphic, first try reimporting the graphic. If the error still occurs, open the graphic in the application in which it was created, resave it with a different name. Make sure that it prints from that application, and then reimport the graphic. If the imported graphic still causes the error, try resaving it in a different format. Or, export it from a different application, or simplify it so that it requires less memory. An imported graphic can cause a PostScript error if it contains damaged or incorrectly written information. It can also cause an error if it is too complex for the PostScript interpreter (for example, it requires more memory than is available).
If the file causes a PostScript error because it is too complex, simplify it and see if it prints. To begin simplifying a complex file, do the following:
Graphic formats such as EPS are updated periodically, so older applications can use an older graphic standard that newer PostScript interpreters can't understand.
