Configure Automatic Receipt Printing

For Epson TM-T88III (3) & TM-T88IV (4) Printers (Scroll down for instructions for the TM-T88II):
In the Print Driver:
We are using version 5,0,3,0 of the Epson TM-T88III print driver; the EPSON TM-T88IV version is ReceiptE4. Register at the EpsonExpert Technical Resource Center website to gain access to the drivers; go to Technical Resources, then choose the printer model from the Printers drop-down list.
Go to your printer properties:
Click Start → Printers and Faxes → Right click the receipt printer → Properties: (XP)
* Advanced Tab, click Printing Defaults button
* Layout Tab: Paper size: Roll Paper 80 x 297mm
* TM-T88III: Layout Tab: Check Reduce Printing and Fit to Printable Width
* TM-T88IV: Check Reduced Size Print; Click OK on the popup window that appears. Fit to Printable Width should be automatically selected.
* OK your way out of there.
In Firefox:
Note: For an alternative see Setting_up_slip_printer_to_print_silently
Under File → Page Setup:
* Shrink to fit page on Format & Options tab
* 0,0,0,0 for Margins on Margins & Header/Footer Tab. This makes the receipts use all available space on the paper roll.
* Set all Headers/Footers to –blank–. This removes all of the gunk you might normally find on a print from firefox, such as the URL, number of pages, etc.
* Click OK
Set the default printer settings in Firefox so you don’t see a “Print” dialog:
* Go to File -> Print
* Set the Printer to the receipt printer.
* Click the Advanced (or Properties) button
* Layout Tab: Paper size: Roll Paper 80 x 297mm
* TM-T88III: Layout Tab: Check Reduce Printing and Fit to Printable Width

* Type about:config, in the address bar. Click “I’ll be careful, I promise!” on the warning message.
* Type, print.always in Filter.
* Look for print.always_print_silent.
* If the preference is there then set the value to true.
* If the preference is not there (and it shouldn’t be in most browsers) you have to add the preference.
* Right click the preference area and select New –> Boolean
* Type print.always_print_silent in the dialog box and set the value to True. This sets the print settings in Firefox to always use the same settings and print without showing a dialog box.
