HP Designjet 4500 Printer Series - Resolving Problems with Printed Images

The print is completely blank
If the front-panel graphic language setting is Automatic (default), try the other settings; PostScript for a PostScript file, HP-GL/2 for an HP-GL/2 file, etc. Then send the file again.
When this particular print is completed, reset the graphic language to Automatic.
The output contains only a partial print
  • If the Cancel button is pressed before all the data was received by the printer, the data transmission is ended and the page needs to be printed again.
  • The I/O timeout setting may be too short. From the front panel, increase the I/O timeout setting to a longer period and then send the print again. Select the (printer) icon, then I/O setup and then Select I/O timeout.
  • There may be a communications problem between the computer and the printer. Check the interface cable.
  • Check to make sure that the software settings are correct for the current page size (For example, longaxis prints).
  • If network software is being used, make sure it has not timed out.
The image is clipped
If the HP Designjet 4500 Printer series is being used, any print liable to be clipped will normally be put 'on hold for paper', and actual clipping will occur only if there is a software error of some kind. On the HP Designjet 4000 Printer series, clipping normally indicates a discrepancy between the actual printable area on the loaded paper and the printable area as understood by the software.
  • Check the actual printable area for the paper size that is loaded.
    printable area = paper size - margins
    The Microsoft Windows HP-GL/2 driver displays the printable area in the Paper/Quality tab.
  • Check what the software understands to be the printable area (which it may call 'printing area' or 'imageable area'). For example, some software applications assume standard printable areas that are larger than those used in this printer.
  • If the image contains its own margins, it may be printed successfully by telling the printer not to add margins to it. In this case:
    printable area = paper size
  • If a very long image is printed on a roll, check that the software is capable of printing an image of that size.
  • Check that the orientation of the paper is the same as that assumed by the software. Following steps changes both the orientation of a print and the orientation of the page. On the front-panel open Printing defaults menu then Paper options followed by Rotate option. It is possible that a rotated image on a roll may be slightly clipped in order to retain the correct page size.
  • The page might have been rotated from portrait to landscape on a paper size that is not wide enough.
  • If necessary, change the printable area in the software.
There is another possible explanation for a clipped image. Some applications, such as Adobe Photoshop, Adobe Illustrator, and CorelDRAW, use an internal 16-bit coordinate system which means that they cannot handle an image of more than 32,768 pixels. If an image larger than this is printed from these applications, the bottom of the image will be clipped. In this case, the only way to print the whole image is to reduce the resolution so that the whole image requires fewer than 32,768 pixels. The HP-GL/2 printer driver contains an option called Compatibility with 16-bit applications, which can be used to reduce the resolution of such images automatically. This option can be found by selecting the driver's Advanced tab then Document options and then Printer features.
The image is in one portion of the printing area
  • Is a small page size been selected in the application?
  • Does the application think that the image is in one portion of the page?
The image is unexpectedly rotated
At the front panel, select the (printer) icon, then Default printing options and then Paper options followed by Rotate. Check that the desired settings are selected.
  note:
For non-PostScript files: If Nesting is On, pages may be automatically rotated to save paper.
The print is a mirror image of the original
At the front panel, select the (printer) icon, then Default printing optionsand then Paper options followed by Enable mirror. Check that the desired settings are selected.
The print is distorted or unintelligible
  • The interface cable connecting the printer to the network (or to the computer) could be faulty. Try another cable.
  • If the front-panel graphic language setting is Automatic (default), try the other settings; PostScript for a PostScript file, HP-GL/2 for an HP-GL/2 file etc. Then send the file again.
  • Depending on the software, drivers, and RIPs that are being used with the printer, there will be different ways of solving this problem.
      note:
    Refer to the vendor's user documentation for details.
One image overlays another on the same sheet
The I/O timeout setting may be too long. From the front panel, decrease the setting and print again. Select the (printer) icon, then I/O setup and then Select I/O timeout.
Pen settings seem to have no effect
Here are some possible explanations:
  • The front panel settings have been changed by selecting the (printer) icon followed by Default printing options then HP-GL/2 settings and then Define palette, but it has been forgotten to select that palette in Default printing options then HP-GL/2 settings followed by Select palette.
  • If software-driven pen settings are required, remember to go to the front panel and select the (printer) icon followed by Default printing options then HP-GL/2 settings and then Select palette followed by Software.
Some objects are missing from the printed image
Large quantities of data may be necessary to print a high-quality large-format print job, and in some specific workflows there may be issues that can lead to some objects missing from the output. Here are some recommendations for the use of the HP-GL/2 driver for Microsoft Windows in these cases.
  • In the Advanced tab, select Document options then Printer features, and set Send Job as Raster to Enabled.
  • In the Advanced tab, select Document options then Printer features, and set 16-bit App. Compatibility to Enabled.
  • In the Advanced tab, select Document options then Printer features, and set Max. Application resolution to 300.
  note:
The above settings are mentioned for troubleshooting purposes and may adversely affect the final output quality or the time necessary to generate the print job. Therefore, they should be restored to their default values if they do not help to solve the problem.
A PDF file is clipped or objects are missing
In older versions of Adobe Acrobat or Adobe Reader, large PDF files could be clipped or lose some objects when printing with the HP-GL/2 driver at high resolution. In order to avoid such issues, upgrade Adobe Acrobat or Adobe Reader software to the latest version. From version 7 onwards, these issues should be resolved.
No output when printing from Microsoft Visio 2003
For more information about problems when printing large images (more than 129 inches long) from Microsoft Visio 2003, see Microsoft's online knowledge base (http://support.microsoft.com/search/).
To avoid these issues, it is possible to scale the image down in Microsoft Visio to a size shorter than 129 inches and then to scale the drawing up in the driver by using the 'Scale to options' in the 'Effects' tab of the Microsoft Windows HP-GL/2 or PS drivers. If the downscaling in the application and the upscaling in the driver match, the result will be as originally intended.
