Is there a Mac virus that disrupts printing function?

We have not been able to print from our MacG3 to HP6mp for about 6 weeks.  Our usual volunteer finally determined that the OS is<:LINEBREAK:>corrupted.  The odd thing is that I took a disk to a partner nonprofit<:LINEBREAK:>to print out a file.  Three days latter, they were getting the same<:LINEBREAK:>print error messages, and were unable to print from their Mac to their<:LINEBREAK:>printer.  Question:  Is there a virus out there that affects Macs that<:LINEBREAK:>corrups the OS and printing functions=?  Note:  we share the same<:LINEBREAK:>volunteer, so something he did or downloaded could be the culprit also.<:LINEBREAK:><:LINEBREAK:>So far, phone-in tech support and our volunteer think we need to rebuild the OS, etc. Any other options? How can we prevent it from happening again?<:LINEBREAK:><:LINEBREAK:>Rebecca Gee<:LINEBREAK:>Women in the Director's Chair<:LINEBREAK:>Chicago, Illinois<:LINEBREAK:>www.widc.org<:LINEBREAK:>rgee@widc.org<:LINEBREAK:>773.907.0610

Hi Rebecca,<:LINEBREAK:><:LINEBREAK:>Because your posting asks a hardware question rather than one about open source software, I have moved it to The Hardware Forum.
