Hi,

I tried on my usual laptop a very simple test: I have two version of my
printer, so I printed the "ugly" file on both, and only one shows the
black stripes.

Unfortunately, nor CUPS, nor Gnome printers app shows any option
dealing with PCL, but I found a reference to PCL in the PPD file of the
"good" one.

Strangely enough, the "bad" printer was installed by HP Toolbox
provided by the hplip package. I need to install a printer with that
package in order to use the scan function, which is extremely important
for me and is almost impossibile to use with the "good" printer.

Having several printers just to manage all the features of the hardware
printer is not very elegant, but as far as it works I could simply
rename the "bad" printer "scanner" and the "good" one "printer", just
to avoid confusion because now they have very long names which differ
just for the last characters.

Thank you again for your advice.
