The enroute charts include complex or dense graphical information that exceeds the capabilities of some printers. Due to the demanding print requirements associated with printing enroute charts, some printers or printer configurations (drivers) have proven inaccurate. The following guidelines may be helpful:
Use the latest printer driver available for your printer. Since drivers are often upgraded after the purchase of a printer, contact the printer manufacturer by phone or via the web to find the latest driver.
Many print problems, especially problems in which the entire image has not printed, are due to inadequate printer memory. For JIFP, use the following guidelines:
Printers that load a full page of data into the printer memory, such as Postscript and HP-GL/2 printers, require at least 2.5MB-3MB of printer memory. Many printer manufacturers recommend 6MB printer memory for complex graphics, especially when printing at 600 dpi.
Some printers, such as many inkjet and color printers, load individual bands of data into printer memory. These printers are commonly delivered from the manufacturer with more than enough printer memory.
In some cases, changing the printer properties improves printing performances or eliminates problems. Try the following options (if they are supported in the printer driver):
Change the graphics mode to Use Raster Graphics.
Change the True Type font option to Print True Type as Graphics.
Adjust the printer memory tracking to Aggressive.
Older printers may not work well with JIFP due to the complex nature of the graphics and limitations of the printer hardware and/or drivers.
