Lexmark print jobs missing characters

We have an in house application that we use to print invoices from a
DOS based screen. It uses a raw data stream to send the print data to
the printers.

- Since upgrading to iPrint we have a weird situation where just our
Lexmark 2490 printers are dropping a single character in about 1 out
of 50 print jobs. Every so often it becomes more prevalent. When
printing reports that are identical we had a dropped character in one
spot on the first print, and a completely different spot on the second
print.

- The line it skips the character on is shorter by that one character,
but the next line is full length, so there is no residual loss of
character spacing.

I have changed to the latest iPrint and Lexmark drivers and the issue
continues.

Obviously, any help is appreciated.

Re: Lexmark print jobs missing characters

Are you using the Novell gateway? If yes, what is your gateway load
string? Maybe you are using a bad LPR name for the printer resulting in
the data being misinterpreted by the printer.

Lexmark print jobs missing characters

Are you printing with use of icapture.exe (and LPT's)? Or are you
submitting it through the windows print path?

Sorry it took so long to answer these...

We are using iCapture.exe to assign printers to LPT ports. We had
previously used 'net use' for this purpose and replaced those
assignments with iCapture.

I just looked at the details of this printer and there is a space in
the name, could that be the cause?

It's easy enough to find out. Just change printername=passthrough to
printername=prt0 in the gateway load string and see if that has any effect.

Please give me simply your gateway load string and I will tell you if it's
OK or not. There is no use speculating on possible bad names if I don't
see what you are doing.

You can find the gateway load string by any of the following means:

1) From iManager, select iPrint -> Manage Printer -> (select your printer)
-> Configuration -> Gateway

Assuming it's a NetWare server:
2) From the server console switch to the Manager screen. select the
pritner and select Information -> Gateway status

3) Use the NDPSADDR.EXE tool from here:
http://www.pcounter.com/ndpsaddr.html

4) In the NDPS\xxxxxxxx.PSM directory, check the PADBTXT.CSV file. It is a
CSV file containing the definitions for all of your printers including the
gateway load strings.

Here is the info requested:

iprintgw PORT=LPR HOSTADDRESS=192.168.111.206 PRINTERNAME=PASSTHROUGH

FYI, We are running Linux OES on this server.

Do you still want me to get the CSV?

PASSTHROUGH is an unfortunate default option which is generally wrong. I
don't know how sensitive Lexmark is to LPR names, but accoring to the
following TID, the official name to use is /prt0

The two printers having the problem are Lexmark printers going through
an HP JetDirect 170x print server (1 port). We have other printers on
these same external print servers and none that we are aware of have
the same problem. The common trait of the two affected printers is
that the iPrint printer name has a space in it (and they are identical
printers).
Today I created a new iPrint printer for each, without a space in the
name, and have switched half my users to the new ones. I will monitor
this for a day and will try the /prt0 fix if this fails.

Thank you.

In that case, it's not the Lexmark name you have to use, but the HP LPR
name. This means the name to use is raw or raw1.

It appears that removing the space from the printer names resolved the
issue. I may change the LPR name to raw if anything else comes up, but
for now I will leave well enough alone.

Thanks for the help

The dropped characters surfaced again, so I have now changed to RAW as
the LPR name. I thought I should give an update in case anyone was
using this to troubleshoot their own issue. I will report back if this
does not fix the issue.

Still having the issue even with the RAW and RAW1 changes made. If I
print the same job to the same printer using 'net use' of a novell
print object (not sure if I am describing this right) it prints
perfect every time. The differences in the 2 print jobs are as
follows:

Print job with dropped character(s) at random spot(s) in the job:

Lexmark 2490 printer
HP JetDirect 170x print server
iPrint Queue
iCapture used to assign LPT3

Print job that prints perfect:

Lexmark 2490 printer
Intel Netport Express 10/100 Print Server
Netware print queue
'net use' used to assign LPT3


So I am looking at the print server itself or iPrint as the culprit. I
really want to tackle this issue, so any questions I can answer to
clarify this I will be happy to.
