#598 how to support Epson SC-T3140
this is not just request for printer driver,
i want to know how to solve problem.
i m trying to make driver for Epson SC-T3140 printer.
I m trying to make Epson T3140 printer driver,
This printer have Epson i3200 heads, 400 nozzles x 8 channels, 4 colors.
I found that its similar with Epson WF7010 series. Just black nozzles.
I guess WF7010 have black nozzles 400 and c m y each 128 . may be.
And original Epson windows printer driver works, resolution works like that , 2400x1200 dpi.
Its because this head size is 1.33 inch , not 1 inch, and have 300 dpi resolution. ( 1.33 inch , 400 nozzles, so 1 inch , 300 nozzles so 300 dpi ).
But I guess our (Gutenprint) softweave algorithm do not consider about head size 1.3 inch.
So I found that WF7010 have black nozzles definintion like this.
Nozzles = 384
base_seperation = 360
nozzle_seperation = 1
hRes – 600, 1200, 2400
vRes – 360 720 1440 …
I set xml like this , actually I m using another code based on gutenprint softweave, may be detail different but almost same work like that.
Then I found sometimes it works well, but still vertical resolution need adjust , I guess this works well then make another code decrease vertical size, that makes result size exact.
But sometimes(almost everytime) do not make print file, or crash execute. I will find where it have error, but I want to know is there anyone who try with this printer. Or similar PRINTER is Epson 4720(4730) printer , same head. A4 size.
Thank you for reading this .
