'"They" claim they did not set-up any kind of a password.' - as Phuxy stated - a password is not needed in any presented 'Authentication' window, if when an account (which must be created) is created, and no password name is entered.
'How do you boot in OS9?', many boot into System 9.2.x via the 'System Preferences, Startup Disk' utility, booting with the <option> key pressed (and selecting either a 'System 9.x' bootable partition or inserted media), or booting with the 'C' key pressed and selecting a 'System 9.x' inserted media. Note: System 9.2.2 is not part of the MacOS X installation, and must be installed manually.
'And why would you have to if you have OSX?', if this is not rhetorical - a number of pre-MacOS X applications simply will not open (run, launch, boot), or run properly, via 'Classic' (a crippled version of 'System 9.2.x') - but, will via a 'System 9.2.x' boot.

What is with all the capitals? (rhetorical), they only prove you know where the <caps lock> key is.

'Now, why in the heck shouldn't I be upset about this? We pay an arm and a leg for this piece of crap (from an Apple store) who has never given us one bit of support. We had an Apple certified tech do the work on the thing and we can't even load a damned printer on it!' - well, so far - you have yet to identify the Mac model; whether or not it originally was purchased with only System 9.2.2 or earlier installed; and, nor did you provide the version of MacOS X installed. So far you stated ...
'We did not "create an account". The thing crashed, died, crapped on us. We had to have a new hard drive installed, along with a new OS. "They" put in OSX. Now we have a machine we cannot work with because it keeps demanding a pasword, "they" said they did not create a password for the thing and we certainly didn't - and by the way, this Mac is the biggest piece of junk we have ever had to deal with! It has been a thorn in our butts for three years now, so, please, don't give me the "Mac we all know and love" line.'
Regardless of what was stated - your Mac (booted with MacOS X) will not operate without an account; so again, regardless of whether you or one of the 'we' did not create an account, someone did. Whether or not, a password was created for said account.
If prior to the hard disk drive failure (and replacement) - only System 9.2.2 or earlier was installed - only then could 'We did not "create an account" be understood. However, none of your previous posts stated such clearly - if implied.
If prior to the hard disk drive failure (and replacement) you did not have MacOS X installed, and only System 9.2.2 or earlier, and then the Office Max technician did install MacOS X (without you, or someone else in the 'we', as an owner of a copy of the MacOS X installation discs) - then it was a mistake on his part. If this is what happened - return to Office Max, with the System 9.2.2 or earlier installation and support discs (all of them) and insist that it is to be installed - not MacOS X 10.?.
And stating 'and by the way, this Mac is the biggest piece of junk we have ever had to deal with! It has been a thorn in our butts for three years now, so, please, don't give me the "Mac we all know and love" line.'' - only now provides a little history (the approx. age) of the Mac. As for the balance of the statement - you are entitled to you opinions; yet, doing such as you have - may limit the number of further responses - to this, and possibly any future posts.
So, if you can and will - please provide the following information:
Mac model.
System version installed on Mac, prior to hard disk drive failure and replacement.
Printer manufacturer and model number.
