I wonder why the blanks are not quoted with '%20', i.e.: usb://EPSON/Stylus%20COLOR%20880
maybe if I changed it to "%20" and see if that makes a difference?
Firefox now refuses to print to that, yet adding the same printer with this port:
usb:/dev/usb/lp0 now works.
See http://portal.suse.com/sdb/en/2004/05/jsmeix_print-cups-in-a-nutshel l.html "The Backends"
For the reason why /dev/usb/lp0 and /dev/usb/lp1 do not work well if there are two USB printers see the old article http://portal.suse.com/sdb/en/2000/03/jsmeix_print-device-usb.html
I do not understand why it depends on the DeviceURI whether in particular Firefox prints or not.
now I DID see where my epson.ppd showed: PPD-Adobe: "4.3" *%PPD file for CUPS/Gimp-Print. *%Copyright 1993-2001 by Easy Software Products, All Rights Reserved. *%This PPD file may be freely used and distributed under the terms of *%the GNU GPL. *FormatVersion: "4.3" *FileVersion: "4.2.7" *LanguageVersion: English *LanguageEncoding: ISOLatin1 *PCFileName: "STP00070.PPD" *Manufacturer: "Epson" *Product: "(AFPL Ghostscript)" *Product: "(GNU Ghostscript)" *Product: "(ESP Ghostscript)" *ModelName: "EPSON Stylus Color 880" *ShortNickName: "EPSON Stylus Color 880" *NickName: "EPSON Stylus Color 880 - CUPS+Gimp-Print v4.2.7" DefaultPageSize: A4 *PageSize A4/A4: "<</PageSize[595 842]/ImagingBBox null>>setpagedevice" this is not good, maybe the A4 made it stop?
The DeviceURI is only needed to tell the cupsd which backend to use and to tell the backend how to send the printing-data to the destination but it has nothing to do with the individual applications which submit print-jobs to arbitrary queues of the printing system.
I understand it "shouldn't" matter, but something is different between my epson and epson-draft printers, yet they are one and the same piece of hardware. and here is one difference: pbc@PaulsPC:/etc/cups/ppd> grep DefaultPage ep* epson-draft.ppd:*DefaultPageSize: Letter epson-draft.ppd:*DefaultPageRegion: Letter epson.ppd:*DefaultPageSize: A4 epson.ppd:*DefaultPageRegion: A4 -- Paul Cartwright Registered Linux user # 367800 X-Request-PGP: http://home.bellsouth.net/p/PWP-pcartwright/key.asc
