I don’t think it’s really fair to slag QW on this.
Computers can still be equiped with parallel ports – you just have to specify one when you buy the machine. Also, parallel port add-on cards are available at every computer shop for $20 or so.
Also, the frustrations in getting DOS printing to work on a current system are not the fault of QW – or any other software vendor, except Microsoft.
To sum up – if NV (Dos) is the ‘perfect’ solution for a company’s bookkeeping, then why is the cost/effort to maintain an environment in which it can be used such a burden? After all, the cost of ownership for DOS NV is zero.
That’s my two cents worth.
