Separator. If your HP LaserJet 4345mfp is equipped with one of these accessories, select the appropriate option. Postscript Passthrough Postscript Passthrough is only available in the PS Emulation Unidriver. It is enabled by default, and must be enabled for most print jobs. Postscript Passthrough provides additional capabilities for some software programs when printing to a Postscript driver. Options such as Watermarks, N-up, and booklet printing might not print correctly from some programs with Postscript Passthrough enabled, because such programs send Postscript information to the product that the driver cannot control. Other programs might print while using these options without problems. Select Disabled and print your document again if you encounter problems. NOTE In some cases, disabling Postscript Passthrough may cause unexpected program behavior. Printer Hard Disk When this option is enabled, the Stored Job option and the Mopier Mode are enabled in the print driver. Use the Stored Job option to store print jobs and then print them later from the control panel. The multiple-original print (mopy) function is an HP-designed feature that produces multiple, collated copies from a single print job. Job Storage If your HP LaserJet 4345mfp is equipped with a hard disk drive, the Job Storage option should be enabled and all job storage options are available. If your HP LaserJet 4345mfp is not equipped with a hard disk drive but has a minimum of 48 MB of memory, limited job-storage options are available. When job storage is enabled, the product can store print jobs so that you can gain access to those print jobs later at the control panel. Mopier Mode The multiple-original print (mopy) function is an HP-designed feature that produces multiple, collated copies from a single print job. Multiple-original printing (mopying) increases performance and reduces network traffic by transmitting the job to the printer once, and then storing it in the printer hard disk. The remainder of the copies are printed at the fastest speed. All documents that are printed in mopier mode can be created, controlled, managed, and finished from the computer, which eliminates the extra step of using a photocopier. The HP LaserJet 4345mfp supports the transmit-once mopying feature when the product has an installed hard disk or a minimum total memory of 48 MB, and the Mopier Mode: setting on the Device Settings tab is Enabled. When you use the HP PCL 6, PCL 5, or PS emulation unidriver, mopying is performed in one of two ways: either through the software or through the product hardware. When the mopier is enabled, mopying takes place through the product hardware by default. One copy of a multiple-page print job is transmitted once through the network to the product, together with a printer job language (PJL) command that directs the product to make the specified number of copies. When you disable the mopier, you are not necessarily disabling mopying, which the driver can still perform through the software rather than through the product hardware (the mopying path that is disabled when you change the Mopy Mode setting to Disabled).
