NOTE:

If you load sheet paper with skew checking disabled, the printer does not measure the length

of the sheet, so the print preview will not be a reliable guide to the final printout.

To preview a print under Windows, you have the following options:

Use your application's print preview option.

Check the Show preview before printing option, which you can find in the driver's

Paper/Quality tab and Features tab. The preview may be provided in different ways,

depending on your printer and printer driver.

To preview a print under Mac OS, you have the following options:

Use your application's print preview option.

Click the Preview button at the bottom of the Print dialog box. This is the basic print

preview provided by Mac OS.

Check the Show print preview option, which you can find in the driver's Printing
dialog, in the Finishing panel.

To preview a print using the Embedded Web Server, select Basic settings > Hold for

preview.

Print 16-bit color images

In a 16-bit RGB image, each of the three primary colors is encoded by a 16-bit value, so that each

pixel takes up 48 bits.

If you print your 16-bit color images through a printer driver, they will be reduced to 8-bit colors before

they reach the printer.

In order to send a 16-bit color image to the printer, you must save it as a 16-bit color TIFF or JPEG file,

then send the file directly to the printer without using a printer driver (see

Using the Embedded Web

Server to print files on page 81

). In this case, color management is done on the 16-bit color image,

and is therefore done more accurately. The image is still reduced to 8-bit colors for final printing.

TIP:

Some applications refuse to save a 16-bit color image in JPEG format; others automatically

reduce it to 8-bit colors. A TIFF file generally gives a higher-quality result, and is recommended.

Change the treatment of overlapping lines

NOTE:

This topic applies only when printing an HP-GL/2 job.

The merge option controls the overlapping lines in an image. There are two settings:

Off: where the lines cross, only the color of the top line is printed. This is the default setting.

On: where the lines cross, the colors of the two lines merge.

To turn merge on, go to the front panel and select the Setup menu icon

, then Printing

preferences > HP-GL/2 options > Enable merge. You can set the merge option from your

software in some applications. Settings in your software override the front-panel settings.
