Enhanced I/O The Enhanced I/O feature allows product memory to be used for storing data received from the host computer. When Enhanced I/O is enabled, you can send more data to the product in shorter amounts of time, which allows you to return to your application sooner. Enhanced I/O has the following options: Auto —allows the product to use Enhanced I/O memory allocation to increase the speed of data transfer from the host computer to the product, if necessary. The default setting is Auto. Off —uses the minimum amount of product memory for storing data sent from the host computer.
Page Protect —allows the formatter to create the entire page image in page buffer memory before physically moving the media through the printer. This process ensures that the entire page will be printed. Page complexity (ruling lines, complex graphics, or dense text) can exceed the printer’s ability to create the page image fast enough to keep pace with the image formation process. If Page Protect is disabled and a page is too complex, the page might print in parts (for example, the top half on one page and the bottom half on the next page). Some print-data loss is likely in these instances, and the product will display an error message.
PJL overview Printer Job Language (PJL) is an integral part of configuration, in addition to the standard Printer Command Language (PCL). With standard ECP cabling, PJL allows the product to perform functions such as: Two-way communication with the host computer through a bidirectional parallel or USB connection. The product can communicate information to the host (such as the control panel status). Isolation of print environment settings from one print job to the next. For example, if a print job is sent to the printer in landscape mode, the subsequent print jobs print in landscape only if they are formatted for landscape printing. EN Formatter system 79
