HPOJ 4110 disappears!

Hello,

This is frustrating!

I am using Mandrake 9.2 with HPOJ v0.90 and CUPS v1.1.9, these were 
installed from the stock Mandrake distro.  I installed the system with 
the HPOJ 4110 connected, via usb cable, and was very pleased to find 
that Mandrake found the HPOJ.  All functions appeared to work correctly: 
scanning and printing.  After a few days of configuring the system, I 
deployed it to the customer location.  This is when the problem showed 
up, in actual use the printer will print for a while and then 
myteriously die!  'lpq' reports that 'Printer is not ready'.

Ok, a little research into the HPOJ docs and it says  that the 
ptal-printd should not be used with cups and to disable it in 
/etc/ptal/mlc:usb:officejet_4100_series by setting init.printd.start=0.  
This seemed to have worked, for a few more days before it died again.

I am at a loss, the only way it seems to get this printer to work is to 
run the Mandrake "Configure your computer | Hardware | Printers", delete 
the printer, then add it again.  Once I do that, it works fine, for a 
few hours or a few days.

How can I diagnose the problem, or fix this?  The customer and end-users 
are getting very annoyed, so am I!

Regards,

TomW
