• Postscript: Postscript level 2 files can be printed on any modern postscript printer, or displayed by a postscript viewer such as Ghostview or GSview. For compatibility with older printers, there is also an option to retrieve a low-resolution version of the document in Postscript Level 1 format, but please avoid this format if at all possible, since these files are very large and often require large resources of printer memory and spooling space to successfully print.
  
  The PostScript page description language was also developed by Adobe Systems, and can be considered a precursor to PDF in many respects. The advantage that Postscript files have over PDF is that most department-size printers today are capable of printing postscript files quite efficiently, so there is no need for an external viewer or printer drivers when hardcopy output is desired. These files should successfully print on any of the modern printers supporting the Adobe PostScript level 2 language features, but some problems have been observed with print engines that don't use the Adobe PostScript interpreter. Postscript level 2 supports the same compression schemes that are used in PDF files, but since it requires ASCII rather than binary encoding of the image data, these files are approximately 20% bigger than their corresponding PDF files.
  
  
• PDF (Portable Document Format): PDF can be viewed using freely available applications such as Adobe Acrobat Reader, GSview, or Ghostview. The document can then be printed using the "Print" menu from any of the above applications. Because of the advanced compression schemes and binary support built into PDF, documents in this format will yield the highest compression.
  
  

• Download Fonts Once
• Use Printer's Halftone Screen
• Level 2 only
  
  

• PCL (Printer Control Language): This printer language is used by printers such as HP deskjets and compatibles. Printing documents in this format may actually be difficult since you need to make sure that the entire document is sent to the printer device as a binary file, bypassing any formatting that the driver may want to perform. Also, the maximum resolution provided for PCL files is 300dpi, so you won't get the same sharpness that you would get from printing a high-resolution Postscript or PDF file.
  
  
• TIFF (Tagged Image File Format): The original TIFF images can be retrieved for local processing or display. This format may be appropriate to further process a scanned page image in order to extract sub-images or to perform Optical Character Recognition (OCR) on it. Please note that only single-page TIFF documents are returned by our system.
  
  
  
  

• Send data to viewer: the full-text article will be sent back directly to the browser which will delegate the display to the appropriate program. For instance, a PDF file will be handed off to the PDF viewer available on the local system (usually Acrobat Reader).
  
  
• Send data direct to printer: the full-text article will be sent back with a signature indicating that it is destined for printing (see section below "Automatic Printing of Articles" for more information). If the browser has been configured to properly handle this media type, the article will be sent directly to the printer, otherwise the user will be prompted for what should be done with the document.
  
  
• Save file on local disk: the browser will prompt the user for a filename to save the document to.
  
  

• Email: articles can be retrieved through email instead of through a WWW browser. If this option is selected, the document will be sent to the specified email address as a MIME (Multipurpose Internet Mail Extension) document. MIME-aware email systems should be able to send the retrieved images directly to the printer, to a file, or to a viewer, depending on what destination option was selected by the user.
  
  
• Compression: for most of the retrieval options, the data can optionally be compressed before they are sent to the user. Unix compress and GNU gzip are the supported compression algorithms.
  
  

    Description:    Remote Printing
    MIME Type:      application/remote-printing
    File extension: .prn
    Application:    (select "Save to File" or enter OS-specific application)

• System V-based UNIX systems (e.g. Solaris):

      lp -c %s
  
  

• BSD-based UNIX (e.g. Linux):

      lpr %s
  
  

• Microsoft Windows (9x, 2K, NT): download and install one of the shareware printing packages gsprint or prfile and then use this entry in as your helper application:

      gsprint %s    (or prfile32 %s)
  
  
  
  

• If you have downloaded an article into a file and can't decipher what kind of data is contained in it, it is probably a gzipped postscript or PDF file, but gunzip or winzip won't uncompress it unless the file name extension is .gz. Try renaming the file to whatever.gz, then uncompress it, and then view/print the resulting file.
  
  
• If Acrobat Reader complains about a PDF file being corrupted, it may be that the file did not download completely because of lack of local disk space or a timeout from the server. In the first case, please check and make sure you do have enough local disk space to handle full-text articles. In the second case, please attempt to download smaller documents by selecting only a small range of pages at a time for download.
  
  
• If you have just changed your article preference settings but your changes don't seem to have had any effect on the full-text articles, you probably need to force a reload of the pages in the web browser in order for it to pick up the new settings. This can be done by clicking on SHIFT + ``Reload (Netscape) or ``Refresh (Internet Explorer).
