3. Update the printer’s firmware. Even if the currently installed firmware version is the latest one,
reinstall it. Send the job using different print settings. The following ones can be helpful:
a. Try sending the job without selecting a paper preset in the driver
b. Try changing the Image Quality settings
c. If you are using the HP-GL/2 driver, try the option “Send job as bitmap”
d. If you are using the PS driver, try using the HP-GL/2 driver instead
e. If you are using the PS driver from an Adobe application (or any other application that can
handle PS), try changing the application’s print settings so that the PS is generated as Raster.
4. Try the following Front Panel settings:
a. Change the Print Language option in the Front Panel from “Automatic” (which is the default
setting) to the language that is being printed (PS, HP-GL/2, …)
b. Queue = OFF
c. Start Printing = After processing
d. For PS SKUs, try changing the encoding setting (“Automatic” by default) to Binary or ASCII
5.
If you are using a 3
rd
party application that does not print through the HP driver, try modifying the
printing workflow by:
a. Using an HP driver
b. Changing the settings in the application’s printing dialog
6. If you are using an accessory Jetdirect card, try using the internal network connector or USB (if
available).
