Gutenprint (reference): works, good grey, an estimated ~30 seconds for the first page
hpijs-pcl5c: works, coarse grey, a little over two minutes to print the first page
ljet4d: works, good grey, 90 seconds for the first page
pxlmono: does not work, prints the print instructions/code
I would say the quality of the output of ljet4d is even better than from the Gutenprint driver.
