Solution

What You Will See


Printing single pel lines using the default installed driver results in:

  • A line which is barely visible.

 

Affected Products

Any laser printer that is compatible with a host-based printer driver.

NOTE: This article does not apply to all printers. If you are experiencing this issue and you are utilizing a different driver, click here for another article that may provide assistance. 


Explanation


The default host-based printer (HBP) driver lacks the ability to affect line thickness.  The PS and PCL drivers do not have this limitation.


Resolution


Single pel lines will appear non-existent or faint in 1200 dpi mode.  Changing the image quality to 1200IQ or 2400IQ or increasing the printer's toner darkness setting should correct this anomaly.  Alternatively, switch to the PostScript or PCL driver. Instructions for carrying out both these procedures are given below.


Adjust the Print Quality Settings


  1. Open Printing Preferences.  To do this, go to Start > Settings > Printers and Faxes or Printers.
  2. Right-click on the printer object.
  3. Select Printing Preferences.
  4. Click the Print Quality tab.
  5. Select Custom.
  6. Change the Print Quality from 600 or 1200 dpi to 1200IQ or 2400IQ.
  7. Place a checkmark next to Toner darkness, as shown, and increase the toner darkness level using the slider.
  8. Click Apply. 



Alternative Fix: Install the PostScript or PCL Driver


If the symptoms persist, try installing the PostScript or PCL driver. These drivers are more advanced in their ability to manipulate print data.
PostScript Driver
  • You can select the PostScript driver when performing a Custom install from the driver installation CD. You can also download the driver from Lexmark's web site. 

PCL Driver  

  • The PCL driver is not currently available, but you will be able to download it in early 2007.
