Our company has been using Quickbooks Online for four years.  We are a Mac only office.  Check printing is a constant crap shoot because of continual alignment problems.  We have purchased Intuit checks and envelopes to eliminate problems.  In the past the alignment issues would pop every 2-3 months but for the last month we have alignment issues every day and the alignment tools and procedures are followed to the letter.  We call tech support and are told switch browsers.  We have tried Chrome, Firefox and Safari and yet we still have daily problems.  Tech support makes us go through the same drill each time and yet we get no resolution.  We only use one computer and printer which has not changed.  We have asked for our problem to be escalated and are promised that a supervisor will call us back... which never happens.  Printing checks is not a "nice to do" thing.  We have payroll to provide our employees and payments due to our vendors.
