Every time I boot the computer I have to reinstall printer

After you install this printer, I suggest that you backup what's in /etc/cups. Then, after you reboot, see what's been changed. That will go a long way with helping diagnose this problem.

I'm not a computer buff, so how do I back up what's in /etc/cups, and how will I know what's changed?

When I type in:sudo dpkg -i --force-architecture pipslite_1.4.0-3_i386.deb, I get:
guy@linuxpc:~$ sudo dpkg -i --force-architecture pipslite_1.4.0-3_i386.deb
dpkg - warning, overriding problem because --force enabled:

Once I have done that the printer works fine but forgets every time I boot.

When I type in the command: piplite-install, I get the following: guy@linuxpc:~$ pipslite-install

[sudo] password for guy:
/usr/lib/pipslite/pipslite-install: error while loading shared libraries: libltdl.so.3: cannot open shared object file: No such file or directory

Is this of any help?

Sure,

Reviewing your claims above "pipslite-install" is found in "/usr/bin" (which is PATH'd unless you've modified your PATH), however contrary to your claim above it does not appear you are running it in that fashion, as the error above indicates "/usr/lib/pipslite/pipslite-install" and it does not exist, or perhaps a conf file is misconfigured for the app. I can honestly say I have no idea what this is supposed to do, sorry.

Even tho, I'd suggest:

guy@linuxpc:~$ cd /usr/bin
guy@linuxpc:/user/bin$ pipslite-install

...and see what transpires.

Good luck.

I tried the commands, but to no avail. "Pipslite-install" is in "/usr/bin" but it is also in "/home/guy/.cups/cups-1.4rc1/usr/bin". What should I do? Thanx!

Oop's my bad, I typo'd that prompt above, not critical. :) The cd was correct however :)

It seems this package requires a shared object library libtdl.so.3 and is not able to find it.

In this thread:

Someone said that libltdl.so.7 existed so he created a symbolic link to this in hopes it would work, you could try this, if it doesn't then you can just remove the link.

guy@linuxpc:~$ cd /usr/lib
guy@linuxpc:/usr/lib$ sudo ln -s libltdl.so.7 libltdl.so.3

If you decide to remove the symlink just remove it where you created it in the /usr/lib directory:

guy@linuxpc:/usr/lib$ rm libltdl.so.3

Also someone suggested downloading the package from the hardy repo and installing it, this can be found here:
