Postscript Passthrough (PS Emulation Unidriver only) Postscript Passthrough is enabled by default, and must be enabled for most print jobs. Postscript passthough 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 printer that cannot be controlled by the driver. Other programs might print 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 application behavior. Printer Hard Disk When this option is enabled, the Job Storage option and the Mopier Mode are enabled in the print driver. The Job Storage option allow you 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 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 9040/9050mfp supports the transmit-once mopying feature when the Mopier Mode: setting on the Device Settings tab is Enabled. When you use the HP PCL 6, HP PCL 5, or PS Emulation Driver, 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 directing the product to make the specified number of copies. When you disable the mopier, you are not necessarily disabling mopying, which can still be performed by the driver through the software rather than the product hardware (the mopying path that is disabled when you change the Mopy Mode setting to Disabled). However, a multiple-copy print job sent with the mopier disabled loses the advantage of transmitting the print job once, since the print job is sent through the network as many times as the number of copies selected. Mopier mode and collation Mopying and collating print jobs are independent but closely related functions. Mopying, the ability to send original print jobs to the product, is performed by the print driver. Collating can be controlled by either the print driver or the document software program. The mopying mode is selected by default in HP PCL 6, HP PCL 5, and PS Emulation Unidriver features 217
