HP LaserJet M4345 MFP - Software Technical Reference (external)

Printer Memory
This option matches the setting to the amount of memory that is installed in the device. The driver
generates ranges of memory that can be selected, up to the maximum that the device can accept. The
driver can use this information to manage how the print driver uses the device memory.
Accessory Output Bin
This control specifies whether tray 4 or tray 5 is installed on the device. The default setting is Not
Installed.
Printer Hard Disk
When this option is enabled, the Job Storage option and the Mopier Mode are enabled in the print
driver. Use the Job Storage 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.
NOTE A hard disk is required for the MFP to perform most tasks. The check box is available
only for troubleshooting purposes.
Job Storage
When Job Storage is enabled, the device can store print jobs so that you can gain access to those print
jobs later at the control panel.
Mopier Mode
CAUTION Disabling Mopier Mode disrupts functionality for the Output and Finishing tab
features.
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 device once, and then storing it in memory. 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 M4345 MFP supports the transmit-once mopying feature when the Mopier Mode:
setting on the Device Settings tab is Enabled.
Use the HP PCL 6, PCL 5, or PS emulation driver to perform mopying in one of two ways: either through
the software or through the device hardware. When the mopier is enabled, mopying takes place through
the device hardware by default. One copy of a multiple-page print job is transmitted once through the
network to the device, together with a printer job language (PJL) command directing the device to make
the specified number of copies.
When the mopier is disabled, mopying is not necessarily disabled. The driver can perform through the
software rather than the device hardware (the mopying path that is disabled when you change the Mopy
Mode setting to Disabled). However, sending a multiple-copy print job when the mopier is disabled
eliminates the advantage of transmitting the print job once, because the job is sent through the network
for each copy.
