The following may be displayed after initiating Test Print or after changing fonts and saving the label.  (View | Warnings and Errors must be toggled on to display errors and warnings.)

Figure 3-X: Error and Warning Messages

A description of the type of error or warning is displayed following the title.  Some of the warnings are primarily informational, such as the “TRUETYPE” warning that is displayed whenever a label with TrueType fonts is saved or test printed.  This warning does not prevent the label from being printed, but it does let you know that the label is being printed as a bitmap, which means the printing of this label is slower.  Some of the warnings may prevent printing of the label, and must be corrected before the label prints at all, or corrected before the label prints correctly.  A common example of this is the “FIELDOFFLABEL” message.  When designing the label, make sure that the entire field is on the label, including the blue selection handles.  An example of an Error may be an error in a datasource formula field, such as a circular reference, which must be corrected in order for the label to print.

Disable Warning/Error Notification – When this check box is enabled, Error and Warning Messages are not displayed.  This may be helpful if you use TrueType fonts most of the time, and you are fully aware that the printing is slower.  As a general rule, however, if this box is checked and a field is off the label (for example), this information is not displayed, and troubleshooting the printing problem may be difficult.  A good case in point would be a field that looks like it is on the label, but whose selection handles are off the label.  A lot of time could be spent looking for this type of error, whereas if notification is enabled, the error/warning is immediately displayed.

USB Errors

If the USB Printer is connected but the port cannot be written to, a “Recoverable printer error” dialog is displayed.  A printer running out of stock, out of ribbon, etc., creates this error.  Once the printer error has been cleared, clicking Retry allows printing to continue.
