Hi
I am not an expert in this area, but have set up named printers for one of my clients.
Can you be more specific about the print dialogs that are appearing? There are three main areas in the application that I know that create print dialogs - posting and printing system reports (e.g trial balances) and then external reports (e.g. invoices, remittance advices).
Posting - have you turned off the posting reports or set them to go directly to the printer without asking?
Reports - reports can be set to go to printer, screen or file and can also have the option to "ask each time" turned off.
Named printers could then be used for the specific items you do want printed and where you want them to go.
Hope this helps.
Cheers
Heather
