Hi Tim, 1284.4 support is problematic for Laserjets with EIO cards. Most of these laserjets are networked so parallel and/or usb support was a minor issue. Or users just used the CUPS "parallel" or "usb" backend instead of the "hp" backend.
The work around for the "hp" backend is to print "raw" instead of over 1284.4. This can be done by setting the hp_laserjet_4000_series io_mode from 6 to 1 in the models.dat file. Since 1284.4 support is a problem for these laserjets, I going to make this change permanent and use PJL to get laserjet status instead of PML. Should be in a future HPLIP release. -dave > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf > Of Tim Waugh > Sent: Friday, October 05, 2007 1:40 AM > To: hplip-devel@lists.sourceforge.net > Subject: [HPLIP-Devel] invalid Dot4ReverseReply packet size > > Hi, > > A Fedora user is getting no luck using their parallel port HP > LaserJet 4000 with HPLIP: > > https://bugzilla.redhat.com/show_bug.cgi?id=249191 > > They've tried 1.7.4a, 2.7.6 and 2.7.7, all with the same > error messages when trying to print a job: > > Sep 21 16:47:10 banach parport0: io/hpmud/dot4.c 243: invalid > Dot4ReverseReply packet size: size=8224, buf=8192 Sep 21 > 16:47:10 banach parport0: io/hpmud/dot4.c 330: invalid > DOT4InitReply: cmd=0, result=20#012, revision=0 Sep 21 > 16:47:10 banach parport0: INFO: open print channel failed; > will retry in 30 seconds... > Sep 21 16:47:40 banach parport0: io/hpmud/pp.c 586: failed > claim_pp fd=5: Invalid argument Sep 21 16:47:40 banach > parport0: INFO: open print channel failed; will retry in 30 seconds... > > Could it be that the HPMUD_BUFFER_SIZE just needs to be larger? > > Tim. > */ > > ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
