When the owner purchased the printer, that is owner equity investment, and either an expense or an asset depending on how you entered the transaction.
The printer was returned - the refund either credits a credit card, or is a deposit in the bank
Whether the owner takes money from the business is a choice and if done it posts to owner equity drawing. it has nothing to do with the previous actions.
Why are you using journal entries? QB is not designed that way. Journal entries should be the exception when using QB, they often do not work as you think they should, and when you use inventory type items they never work for inventory. It is much better to use the forms on the home page the way QB is designed to be used. Journal entries also bypass accrual/cash reporting, and will not show on many reports.
For a company taxed as a sole proprietor (schedule C) or partnership (form 1065), I recommend you have the following for owner/partner equity accounts (one set for each partner if a partnership)
[name] Equity (do not post to this account it is a summing account)
>> Equity
>> Equity Drawing - you record value you take from the business here
>> Equity Investment - record value you put into the business here
