The MFP's multitasking capability enables multiple functions to proceed simultaneously. The HP LaserJet 4100 mfp series' digital-sending is similar to faxing information, but offers significant advantages. You can send e-mail to multiple e-mail addresses simultaneously, saving time and delivery costs. The privacy is ensured by sending information directly to e-mail in-boxes rather than to a fax machine, which might have many users. Digital sending allows delivery of files at near-original quality in black and white or in color. You can send files in PDF, JPEG, TIFF, or M-TIFF file formats, which can be modified by the recipient as needed. The product offers efficient copying services for the workgroup. Making a copy is as easy as pressing the START button to use the system defaults. The product offers full office copying functionality. The product is fully compatible with other HP LaserJet printers. When the installation software is loaded, network printing is available through the HP Jetdirect 10/100Base-TX print server card that is supplied with the product. Use the parallel port or the optional Fast InfraRed receiver (FIR) port for direct printing. The HP LaserJet 4100 mfp series allows full multitasking capabilities to enhance office efficiency. System defaults can be set to define how multiple incoming jobs are managed and how these defaults can be overridden to meet special requirements.
