BASIC CONCEPTS
Font memory
Increasing font memory improves processing time for
applications that require large fonts or a large number of
different fonts on a single page. In the pass through mode, the
LPS prints up to 128 fonts on a single page. In normal mode,
the amount of fonts per page that the LPS prints depends on the
font definitions for the emulated line printer. When processing
the page data, the controller stores font information in a special
memory cache called font memory. The amount of memory
required to store font data depends on the size of the fonts and
the number of different fonts on a single page.
If your applications call for either large fonts, or a variety of fonts
on a single page, the increased font memory option can greatly
improve the processing time required to print these documents.
Custom fonts, logos, and signature font data also consume font
memory during processing.
Paper
Paper sizes Laser printing systems print on the following paper sizes:
• 8.5 by 11 inch (216 by 279 mm)
• A4 (8.27 by 11.69 inch, 210 by 297 mm)
• 8.5 by 14 inch (216 by 356 mm).
Paper types A large variety of paper types can also be used on the LPS:
• Label stock
• Transparencies
• Predrilled
• Perforated
• Colored.
Paper weights and printing speed vary with each printer.
Image size considerations
Your LPS can print on a variety of paper sizes. You can
manipulate the size of the image with some limitations.
Understanding the terms system page, physical page and virtual
page helps to define these limitations.
System page
This refers to the maximum image area, which is 8.6 by 14.00
inches. Elements which do not print may originate off the
leading edge of the system page.
Refer to the “Non-imaged elements” subsection later in this
chapter for more information.
