Sorry for the unclear post earlier. I am definitely not a novice when it
comes to computers, but didn't really think this through when asking my
question.
I have seen Printer Offline messages on numerous computers, both at home and
on computers we support at my job. Let me start with those. At my work,
customers call in for support on problems they have with their shipping
systems, I am not going to provide which company for privacy and security
reasons. But here's the rub. Our customers call in reporting that their
Eltron and Zebra thermal label printers no longer work. They just WILL NOT
print anything, not through our software, nor through Windows. There are a
few other printer models models we use with our software as well, but these
are the most prevalent. We look at the printer properties and see the
status as "Offline". It doesn't seem to matter whether the printer is
connected using a USB, or serial connection either. Cancelling the print
queue doesn't seem to work, because Windows just won't let it go. This
works only when the printer is online though. So we have gone into
Windows\System32\printers and deleting the contents. (I have not found this
folder in Windows 7 though and am wondering where Microsoft hid that too.)
This clears the print job, however it does not do anything to bring the
printer online. Yes, we have disconnected the printer and plugged it back
in after resetting the printer using a "dump mode". We still cannot get the
printer to read as online ad nothing will print to it. So, the next step is
to uninstall and reinstall the label printer driver. Sometimes this works,
but sometimes it doesn't. We have even gone so far as to set the printer to
print directly to the printer and avoid spooling in the printing
Preferences. This works great when print jobs continually get stuck in
spooling, but again does nothing to get the printer back online. We only
do this when there are spooling issues and the customer is not doing a lot
of shipping volume. Funny thing here too is that whenever we disconnect the
printer and reconnect it, Windows wants to reinstall the driver, even if the
printer just needs resetting to align the labels and the issue has nothing
to do with stuck print jobs. When this happens, we end up with duplicate
printers in the Windows device manager and Printer folders with copy 1, or
copy 2 etc. This is a problem because our software needs the printer to be
named correctly in order for the printer to work.
So here you have the full story. I am looking for something/anything that
will make my life easier with this issue. At home I am using an HP DeskJet
D1520. This printer is connected using a USB 2.0 connection to the
computer. There were several times when the printer will stop responding
and go offline. I have had to delete the printer and reinstalling to get it
back online. With all of the printer issues revolving around the same
issue, I'm wondering just where these are coming from. Is it Windows, or a
driver issue.
I really would like to have your thoughts on this. Any help will be
appreciated.
