After turning on printer, prints initial "blank" sheet

You can fix this by turning off bidirectional support:

- Right click your printer, select properties
- go to the ports tab, uncheck Enable bidirectional support.

Your printer has to be turned on before printing.

That fixed the extra page printing S1M problem for me.

Sometimes the error of "Printer Printing Blank sheet" There are some common reason behind this error:-

• The problem can occur if the pages you are using for printing requires more ink than the standard metric.
• Clogged nozzles in the printhead can be responsible for the low yield of cartridges. Epson printer has reduced the diameter of the nozzle for enhancing the printing quality. The small diameter leads to a clog easily.
• The problem can arise if you are not using original Equipment Manufacturer's cartridges. A third-party seller will not give you genuine cartridges.
• If you have not cleaned your printer for an extended period, dust accumulates inside the printer and restrict your printer to print properly.
• When you do not use your printer regularly, then ink in the cartridges will either dry up or clog in the printhead.
