Litigation Support Tip of the Night

When printing PDFs it's possible to experience a postscript error.  (Postscript is a page description language that allows for on the fly rasterization which interprets text and images as straight lines and curves.)  The first several pages of the print-out may appear normal, but the document can be cut off at the end with missing pages and a final blank page with an odd message at the top left:

ERROR: undefined



When a got this error message at the end of a PDF print-out today (the PDF itself worked normally) I was able to fix this problem and print the full hard copy by accessing the advanced settings for the printer.   Disabling the setting for "PostScript Pass through" (on a Konica Minolta 558) did the trick.

The Printliminator is a bookmarklet that can be used to customize print versions of web pages.   I tested it tonight with with Internet Explorer.  It's available at, .  Simply drag the bookmarklet onto the links part of the browser (in IE look for the yellow star icon on the left.)   

When you click on the bookmarklet a small dialog box will appear.  If you select 'ADD PRINT STYLES', red boxes will appear around the various sections of your current web page.   Clicking on any one box will remove it from the browser.   If you press ALT and click on a red box it will be isolated in the browser so you can print just it alone. 

Ignore the option in the Printliminator dialog box to 'SEND TO PRINT'.   Instead use the regular print function in your browser.

If you are using a VM Ware remote desktop and are locally connected to printers set up at a remote location (not your office network), be careful about switching which USB ports are used for the printer.    VM Ware will continue to assign a printer to the USB port used first, and while you may still be able to print, jobs may be slowed down considerably.   See a post about this issue on the VM site.   My own recent experience confirms this problem.

Page Description Language is a computer language that used to represent a file, such a Word document, to the Raster Image Processor in a printer.   The Raster Image Processor interprets the data as a bitmap, or a  grid of pixels.  

There are three very common page description languages, and each has its own advantages and disadvantages. 

PCL  (printer command language) - is the HP page description language.   It uses simple commands that don't require expensive printer controllers.    It is good with low cost printers, but doesn't allow for high precision in printing or the use of a full range of colors.

PostScript is a page description language developed by Adobe.  It uses code to describe text and graphics that is text itself that can be reviewed in a text editor.   The PostScript language has applications beyond just printing.   Its dictionary feature allows for pages to be generated from files based on data inputted on the printer.   PostScript was developed to ensure that different devices would print files the same way.

PDF - this page description language is focused on printing as close as possible to the image displayed on the screen.
