CONTROLLER FUNCTIONS
2.2.5 PROOF PRINT
Host Computer
The Proof Print function gives users a chance to check the print results before
starting a multiple-set print run.
When printing from a host computer, a print job is sent to the controller with a user
ID and the current time. Then the controller executes raster image processing
(RIP), stores the image data onto the collation partition of the hard disk, and prints
one set of the document (step [1] in the above diagram). Then the controller moves
the raster image file to the proof print partition of the hard disk (step [2] in the
above diagram).
After the user checks that the print result is OK, the user selects the file using the
machine's operation panel, and print the rest of the sets (step [3] in the above
diagram). After all sets have been printed, the controller deletes the file
automatically.
If the proof print result is not OK, the user must delete the file manually.
If there is no available space for a new file in the proof print partition, the controller
deletes the file from the collation partition after printing the first set, even though it
cannot copy the file to the proof print partition..
NOTE: 1) Proof print requires the installation of an optional hard disk.
2) The proof print partition size is about 600 MB. It can hold up to 30 files
or 2,000 pages. The maximum number of pages depends on how
complex the pages are.
3) Proof print is available with the PCL drivers, the Windows 95/98
PostScript driver, and the Macintosh PostScript driver (with the Proof
Print plug-in). The PostScript drivers for Windows 3.x and Windows
NT4.0 do not support the proof print function.
