 This problem also exists on my Emachines Celeron 600 running
 FreeBSD 6.4 using the escputil program with an Epson printer.
 I have the parallel port set to NIBBLE mode that may be part
 of the problem.  However, the Epson has to use NIBBLE mode to
 talk to the computer.  Here's a snippet of the dmesg:
 
 ppc0: <ECP parallel printer port> port 0x378-0x37f,0x778-0x77f irq 7 drq 
 3 flags 0x1 on acpi0
 ppc0: Generic chipset (NIBBLE-only) in NIBBLE mode
 ppbus0: <Parallel port bus> on ppc0
 ppbus0: IEEE1284 device found /NIBBLE
 Probing for PnP devices on ppbus0:
 ppbus0: <EPSON Stylus C84> PRINTER ESCPL2,BDC,D4
 plip0: <PLIP network interface> on ppbus0
 lpt0: <Printer> on ppbus0
 lpt0: Interrupt-driven port
 ppi0: <Parallel I/O> on ppbus0
 
 cat /boot/loader.conf
 hint.ppc.0.flags="0x1"

 To demonstrate the problem
 
 cd /usr/ports/print/gimp-gutenprint
 make install
 cd work/gutenprint-5.1.7/src/escputil
 make install

 Setting lpt0 back to interrupt driven mode then makes the
 escputil program get the device busy error message again
