Name - the name of the letterhead
Description - an appropriate description

In the standard Letterhead.jrxml the space allowed for the letterhead is 280 pixels wide, 100 high. If your logo differs from this it will be scaled to fit whilst retaining its shape. NOTE: if you mistype the file name, then no error will be reported but the logo area will be blank on the printed documents.
HTML Logo URL - a URL to the practice logo. This can be used in email templates.
Base URL - a URL prefix used to help construct templates that refer to resources located at a common base path. These could be images, HTML, or plain text for example. The resources must be publicly accessible. When populating the field, it should always containing a trailing slash.

Note that if you do use say 'MyPracticeLH', then you will also need to provide you own address block subreport with the content name 'MyPracticeLH Address Block.jrxml' and this can be cloned from the standard Letterhead Address Block subreport.

Letterhead Page 1 Only - check this box if you use pre-printed letterhead paper but only for the first page (and your printer is set up to print the remaining pages on plain paper). Leave it unchecked otherwise. The setting of this option is ignored unless the Plain Paper option is unchecked.
Use Product Types - check this box to show the product type on each line item in invoices, credit notes, estimates and statements. The line items are grouped by product type and ordered by the product type's Invoice Sort Order. This option is not available on A5 format documents because of lack of space.
Reminders on Invoice - check this box to display on invoices any patient reminders due in the next 12 months.  A maximum of 4 lines are shown with reminders for products of the same product type on the same day for multiple patients combined on the one line.
Appointments on Invoice - check this box to display on invoices any appointments in the next 12 months.  If there are more than 3 then only the next 3 are shown.

The following fields are use to control messages added to various documents.

The following fields affect the Debtors Statements. They are used to determine what payment instructions are shown, and whether or not Invoice line items are shown:

Credit Card Instructions - if you accept payment by credit card, enter the instructions here, else leave blank
Direct Deposit Instructions - if you accept payment by direct deposit (or other electronic payment method into your bank account), enter the instructions here, else leave blank. If the characters '[REF]' are present in the text they will be replaced by a reference code. This will consist of the first 5 letters of the customer name followed by their customer ID. Hence if Mr Fredricks is customer 34567, the reference code will be FREDR34567.
Payment Option 3 - if you have a 3rd payment option (for example by cheque), enter its instructions here, else leave blank.
Payment Option 4 - if you have a 4th payment option, enter its instructions here, else leave blank.

If the latter, then the line items are shown if the invoice's Print flag is not set. (This flag is set when the finalised invoice is printed - emailing or previewing does not set the flag.)
 

Reminder Message - this message is added to the end of the Grouped Reminders document.
