Getting Help When Things Go Wrong 
4
I have a USB cable, 
and when I try to print I get 
a message saying “There 
was an error writing to 
LPT1.”
You may not have plugged 
your USB cable in before 
installing the software.
1 Disconnect the USB cable from your 
printer.
2 Insert the printer software CD (or Disk 1 if 
you have diskettes) into your computer.
3 Click Start Run.
4 Browse the CD, select Setup, then click 
Open.
5 The setup.exe file will appear in the dialog 
box. Click OK.
6 Select the Remove HP DeskJet 930C 
Series software option to remove the 
software.
7 Connect the USB cable to your printer 
again. The USB installation screen should 
appear again.
8 Repeat the “Install USB software” step. See 
your Quick Start Poster or page 50 in this 
User’s Guide.
My printer is 
connected with a USB cable 
through another USB 
device or a hub and when I 
try to print I get a message 
saying “There was an error 
writing to <name of USB 
port>.”
Your printer may not be 
getting good data from the 
other device or hub.
Connect the printer directly to the USB port 
on the computer.
