Chapter3 Handling Restrictions on Using the Printer Driver • The printer driver does not support printing a background image. • To print multiple print jobs in time order, disable [Print spooled document first]. If the printer driver receives multiple print jobs with [Print spooled document first] enabled, the print jobs may not be printed in time order. • When using Epson printer driver, do not change the control prefix, the format prefix, and the delimiter string that are included in ESC/Label command from their defaults. If you change them, printing will not be performed or result in producing unintended printouts.
For their default settings, see "Operation Panel Settings" on page 223 and find [Printer Settings] - [Print Settings] - [Command Character]. 139
