Max print length Epson ET-8550 macOS
Posted: Sun Apr 27, 2025 6:01 pm
I need to make a 13 inch by 30 FOOT print using my ET-8550. Does this software make that possible? Thanks
Hello, the maximum print length in the PrintFab driver for the ET-8550 is 129" / 327cm. However, with most Epson printers it is possible to print longer.
I recommend to install the 30 day trial of PrintFab which is available for download at
https://www.printfab.com -> link "Download"
After installation, you can modify a text file to allow longer custom sizes:
Please open the app "Terminal" (in "Utilities") and enter
sudo pico /library/printers/printfab/printers/Epson_EcoTank_ET8550.tpp
to edit the driver description text file for the ET8550 in a text editor (your login password will be requested).
Then search for
[Size0]
Name=Custom
Custom=1
Minsize=2130,3390
Size=12950,129000 ;paper length 129" tested & worked
Margins=120,120,120,120,540
Param=99,0,0,0
with the key combination "CTRL"+"W", then enter "Size0".
Then increase the second value in the line "Size=..." from 129000 to e.g. 360000 (maximum print length 360 inches).
Then save the modified file with the key combination "CTRL"+"X" and the key "Y" for confirmation to overwrite the existing file.
Then open the "PrintFab Toolbox " application, button "Open toolbox for selected printer", button "Custom page sizes" and you can add a page size of e.g. 8.5 x 360 inches.
