A lot of people seem to have problems with the HP LaserJet P2015 on a

network.  My problems were not associated with networking--I'm

connecting to the printer with a USB cable.  Instead, my problems seem

to stem from this printer's alleged incompatibility with lpd, as

mentioned at
 http://www.macintouch.com/readerreports/printing/topic2869.html#27aug2007
(But I've been told that this printer works fine if CUPS is used instead

of lpd.)
I'm using lpd with the following line in my printcap file
 usb:lp=/dev/ulpt0:sd=/var/spool/output/usb:sf:sh:tr=^D:
The beauty of PostScript printers is that this is all the configuration

that is needed.  The "sf" prevents an extra blank page from being

printed with every job.  The "sh" prevents a page of garbage (the

so-called "burst page") from being printed with every job.  And the

"tr=^D" tells the printer that it has reached the end of a job.

(Without the "tr=^D", the printer hangs after the first job.)
This setup worked fine with my old HP LaserJet 1200, and a similar

configuration should work for any PostScript printer.  Unfortunately,

the HP LaserJet P2015 crashes on certain printjobs with this setup.
