Background
This support article explains how you can set a default form for printing (i.e.: a default check to be printed, a default statement to be used, a default form for printing a Purchase Order).
The steps below are based on a sales invoice - but this is very similar throughout the software.
Setting a Default Form
To set a sales invoice form as the default:
Go to the Sales module
Click on Print/Email invoices
Click on the Advanced Filters button
At the top of the Advanced Filters window set the type of sale layout you use (ie: service, item, professional)
At the bottom of the Advanced Filters window click the drop down menu in the Selected Form for Sale field
Select the form you wish to use as default and click Use
Click OK to close the Advanced Filters window
Click Cancel to close the Review Sales window
Although these are the steps for sales invoices - you can find the same options in Sales > Print/Email Statements, Purchases > Print/Email Purchase Orders, Banking > Print Checks and Payroll > Print Paychecks. In the Print window click Advanced Filters and then change the Selected Form to the form you wan to use as default.
