Print-quality issues ● If you have defined a custom page size with very narrow margins, the printer may impose its own minimal margins, clipping your image slightly. You may want to consider using a larger paper size, or borderless printing (see Select margins options on page 56). ● If your image contains its own margins, you may be able to print it successfully by using the Clip Contents by Margins option (see Select margins options on page 56). ● If you are trying to print a very long image on a roll, check that your software is capable of printing an image of that size. ● You may have asked to rotate the page from portrait to landscape on a paper size that is not wide enough. ● If necessary, reduce the size of the image or document in your software application, so it fits between the margins. 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. NOTE: An image 32,768 pixels long would print at a length of 54.61 in or 1.39 m if you select Best or Quality in the driver, 109.23 in or 2.78 m if you select Fast, Normal or Speed in the driver. If you try to print an image larger than this from these applications, the bottom of the image may be clipped. To print the whole image, try these suggestions: ● Try using the PostScript printer driver to print your job, if you have not already tried it. ● The Windows HP-GL/2 and HP RTL driver dialog includes an option called Max. application resolution, which enables you to print successfully in this situation. You will not normally need to change the default setting, which is Auto. However, you can find the option in the Advanced tab, under Document Options > Printer Features. ● Save the file in another format, such as TIFF or EPS, and open it with another application. ● Use a RIP to print the file. 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 suggestions to help you to avoid this problem. ● Try using the PostScript printer driver to print your job, if you have not already tried it. ● Select a smaller page size and scale to the desired final page size in the driver or in the front panel. ● Save the file in another format, such as TIFF or EPS, and open it with another application. ● Use a RIP to print the file. ● Reduce the resolution of bitmap images in your application software. ● Select a lower print quality in order to reduce the resolution of the printed image. 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 and HP RTL driver at high resolution. In order to avoid such problems, upgrade your Adobe Acrobat or Adobe Reader software to the latest version. From version 7 onwards, these problems should be solved.
