If you are using the new 4550 printer, simply follow the instructions below and you will have no problems and you will acheive the maximum results with the least effort.
Step 1
Using the software that came with your printer, place the CD in the CD drive
Step 2
Click on INSTALL
Click NEXT
Click YES
Click NO (if you want to use the Internet site from HP you can click yes here)
(Continue if you are not using networking)
Click NEXT
Click NEXT
Click CUSTOM Installation
Step 3
Under Components: uncheck PCL6 driver
Click PCL5 driver
Now you should have a check mark in the box next to PCL5 driver and the PS driver.
You will also want a check mark in the FONT program
Click NEXT
Click FINISH
When you have finished you should have1 driver for PostScript and 1 for HP-4500. Nothing else is needed. Remember that when you are using Corel Draw you will have a choice between two printing methods. The HP PCL5 is for printing Raster graphics which are very simple graphics. Everything you create in Corel Draw without using a scanner or photos is considered a simple graphic and should be printed with the PCL5 driver. All vector or LPI images should be printed with the Postscript driver. Anytime you use a scanned image (such as a JPEG) you will want to print it with the Postscript driver. The only exception is when you scan something and convert it to a bitmap. A bitmap is a DPI image, not a LPI image and should be printed with the PCL5 driver. Your printer prints in 600 DPI and 2400 LPI. This is why you will get great color correction simply by choosing a driver or program that matches with the graphic you are using.
