A message at your system controller terminal notifiesyou of the unsupported feature and gives you theopportunity to continue or end the task.• 4245 emulation using channel connections to an IBM hostemulates an IBM line printer.Electronic printingElectronic printing is the integrated production of documents ondemand, using digitally stored documents and graphic images,computerized composition techniques, and electronic printingsystems such as the 4050/4090/4450/4650 LPS.Electronic printing allows you to use a variety of printingapplications and produce complex documents ranging frombooks and lengthy reports to invoices, statements, forms, andlistings.AdvantagesElectronic printing has several important advantages overtraditional printing methods:• Minimizes the use of preprinted forms in listings, statements,invoices, and so on. You can create forms electronically,using a wide range of design elements such as lines, boxes,graphic images, and a variety of fonts. You can thenautomatically merge the forms with variable data.• Electronic printing lets you create documents and forms in ashorter time with greater control over the result, includingthe ability to make last-minute changes.• By giving operators and programmers the capability toprogram the print job processing, repetitive jobs are handledeasily and consistently, and the output potential of theprinter can be maximized.• The programming capability, combined with a variety ofhardware configurations, makes it possible to producedocuments with cover-to-cover control. For example, youcan print different pages of a report on different paperstocks, and the output can be collated or stapled. Electronicprinting eliminates the separate handling and finishingprocess of traditional printing.1-2 XEROX 4050/4090/4450/4650 LPS PRODUCT REFERENCE
