Specify whether or not to automatically reduce or enlarge a received image to print it at the real size (the specified dimensions).
Settings
Off
On
Default: On
Operations
If "Off" is specified, images are not printed at the real size. They are printed at full size (dot-by-dot).
If either of "8. Reproduction Ratio", "J. Reduce/Enlarge Ratio: Horizontal", "K. Reduce/Enlarge Ratio: Vertical", and/or "P. Auto R/E to Printable Area" has been configured, or if either of the "mag", "xmag", "ymag", "fit", "nofit", and/or "autoreduce" printing option is specified, the image is reduced/enlarged at the ratio calculated by multiplying its reproduction ratio by the reproduction ratio specified in "T. Auto R/E to Scanned Image Size" to print it at the real size, even if "On" is selected.
This setting is ignored on image data in any format other than TIFF or CALS.
A reduce/enlarge ratio can be calculated from the horizontal and vertical resolution information in the tag of the TIFF data and the printing resolution. For example, when printing TIFF data, which has the horizontal resolution of 200 dpi and vertical resolution of 400 of dpi specified in its tag, on the machine at a resolution of 600 dpi, the image size is enlarged 3.0 times (600/200) horizontally and 1.5 times (600/400) vertically when printed.
Images in multipage TIFF data are reduced/enlarged based on the resolution information of each page.
Conditions
If the received TIFF or CALS data does not contain the resolution information tab or the page or header record, this setting is ignored even if "On" is selected.
If the "tifffit" or "notifffit" printing option is specified, this setting is ignored.
If the "autoreduce" printing option is specified along with either of the following items, the setting for "autoreduce" or "b. Auto Reduce" is given priority over this setting.
"On" is specified for "P. Auto R/E to Printable Area".
The "fit" printing option is specified.
