LineJet jams continue to require power-cycle
The HP 3000 division showed evidence that it is making
HPs printer group more aware of the business server, to improve
communication between MPE/iX and the latest LaserJet products.
A
crowded meeting of SIGPrint at HP World uncovered a long-awaited
patch that will permit MPE/iX to communicate completely with the
newest of HP LaserJet printers. But LineJet and LP printer users are
still looking for a smoother fix for the 3000 operating system to
avoid a power-cycle when those printers jam or run out of paper.
Patches MPELX39A (for 5.5) MPELX39B (for 6.0) and MPELX39C
(for 6.5) specifically address the JOBID function which was
causing endless printing when using the setting
PJL_SUPPORTED=TRUE. Customers want to use PJL to enable page-level
recovery (PLR) from errors during long print jobs. HP said when
placing the patches in general release that At the current time
the Worldwide Technology Expert Center is not aware of any problems
with page level recovery on LaserJets with MPELX39
installed.
CSY is engaged with the printer division in
Boise, said CSY manager Ginny Bratrud at the meeting.
Theyve let us know that theyve got some new
products coming out, and well make sure that we can get some
testing done on the 3000. We can make sure their new products are not
going to break when you hook them up on the 3000.
The A and B LP Series printers need to be upgraded to C
level firmware to enable PLR, Bratrud said. In order to get the
latest function code supported on the As and the Bs, theres a
lot that has to go into that, she said. The memory that
is in those printers is not big enough to support the [new function
code for PLR.] You need to upgrade the memory, and upgrade to the
newer C board to make it work.
Smith-Gardner MACS sites cant use the upgrade at
this time, because it can slash printing speed of LineJets. Shipping
manifests
contain some extraneous font-directive characters
prepended to nearly every line of output. With the new firmware
upgrade, each line
caused a noticeable pause to occur in the printer,
reported Chris Bartram, a consultant working at the US Mint.
This pause effectively slowed the printer down to a fraction of
its original speed.
Bartram noted the LineJet fixes for printing cost more
than $1,000 per printer in new hardware. The upgrade required
new memory chips to be purchased and installed in the printer,
he said. The firmware upgrade itself was downloaded into flash
memory. We spent about $10,000 in parts for upgrade kits for the 6-8
line printers we have installed; none of which were more than a year
old at the time.
Other sites can deploy the new function code and
power-cycle their printers in the event of a paper out or jam. The
MPE spooler then communicates with the printer and does a silent run
in the printers view box. Data is sent to the printer, the
printer interprets it, but does not start printing until the printer
reaches a target starting page specified by the spooler. The printer
begins printing on the page where the jam occurred, or will
back up a couple pages, Bratrud said.
We know a lot of you dont want to do the power
cycle, she added. CSY is still working with the LineJet and LP
engineers to see the differences in behaviors of the printers,
and see what it would take if we made an investment [to fix the
problem]. HP has only begun an investigation of what would be
required to fix the problem without a power cycle.
Not the best of solutions, Bratrud admitted, but HP
continues to work on the problem. A white paper that details the
workaround for LineJet PLR is at the HP LineJet Web site at www.linejet.hp.com/info_library/pdfs/plr092899.pdf
Bratrud also noted that the new LineJets introduced in
February with an internal JetDirect network card can experience hangs
while working with the bundled MPE/iX print spooler. A fix is
available for the function code inside these printers. LineJets
shipped after August are not affected, as they have the new function
code already loaded. LineJets using external JetDirect units
arent affected. Customers can get the new code by contacting
Bratrud via e-mail at ginny_bratrud@hp.com.
We want to make sure the customers have all the
pieces in place, Bratrud said. The escalation manager
walks them through the process.
HP
is still trying to understand why performance degrades on printing
using the LP and LineJets with MPE/iX barcode applications, Bratrud
said. HP engineers have been able to duplicate the problem.
The SIGPRINT meeting was one of the first to include an
official support representative from HPs Boise LaserJet
organizations. Bringing the HP 3000 and other non-Windows servers to
the attention of HPs printer support team has been a long
process. Bratrud said that help from the Response Center will now
include a team knowledgeable in printer problems.
When you call its not going to be someone who
has server knowledge and no printer knowledge, Bratrud said.
This team will handle all the printer calls in a better and
proactive manner.
The finer points of understanding computers other than PCs
still might be outside the grasp of printer experts, however. Product
marketing rep Pat Cooper from the LaserJet Solutions Organization
assured a room full of HP 3000 customers that Boise has engineers who
understood their servers. But Cooper didnt seem to understand
which operating system runs the 3000.
We are trying to focus on non-Windows applications,
which in some ways is kind of unheard of in Boise, Cooper said.
He explained that the Boise Hardcopy Customer Care Centers 700
support engineers include six that are Unix engineers. All you
need to do is tell the support center you need a Unix engineer, to
get into our advanced technical support team. Support from the
Hardcopy Center where there may or may not be MPE/iX-savvy
engineers is available at 208.333.2551.
Hopefully, we can go forward so theres no
problems when you plug a new printer in, Bratrud said. The 3000
divisions R&D manager Dave Wilde said CSY understands that
enterprise printing is a business issue for its 3000 customers. Since
MPE networked print engineering happens in the divisions Indian
offices, Wilde said, I was on a lot of those 6 AM phone calls,
so I think we do understand the importance of that.
