If you under XP Embedded an Epson POS printer, eg Epson TM-T88III, TM-T88IV and TM-T88V tried to install, it can cause the following error messages:
Unable to install printer driver EPSON TM-T88III Receipt. Error Code = 126.
The specified module could not be found.
Error Code = 1797. The printer driver is unknown.
This is because the in XPe many files are missing, which are otherwise available in XP. The files you need from an XP on your XPe:
I have now found it, that other printers installed under XPe only work if these same files are present. Especially when there are large installations, such as HP who want to install a whole suite..
