BASIC CONCEPTSFont memoryIncreasing font memory improves processing time forapplications that require large fonts or a large number ofdifferent fonts on a single page. In the pass through mode, theLPS prints up to 128 fonts on a single page. In normal mode,the amount of fonts per page that the LPS prints depends on thefont definitions for the emulated line printer. When processingthe page data, the controller stores font information in a specialmemory cache called font memory. The amount of memoryrequired to store font data depends on the size of the fonts andthe number of different fonts on a single page.If your applications call for either large fonts, or a variety of fontson a single page, the increased font memory option can greatlyimprove the processing time required to print these documents.Custom fonts, logos, and signature font data also consume fontmemory during processing.PaperPaper 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 considerationsYour LPS can print on a variety of paper sizes. You canmanipulate the size of the image with some limitations.Understanding the terms system page, physical page and virtualpage helps to define these limitations.System pageThis refers to the maximum image area, which is 8.6 by 14.00inches. Elements which do not print may originate off theleading edge of the system page.Refer to the “Non-imaged elements” subsection later in thischapter for more information.1-4 XEROX 4050/5090/4450/4650 LPS FORMS CREATION GUIDE
