 |

I have printer Epson L132. I downloaded from this page http://download.ebz.epson.net/dsc/du/02/DriverDownloadInfo.do?LG2=EN&CN2=&DSCMI=34541&DSCCHK=141ba614c212ead0099d27f8dc8f2bc35faf7781 epson-inkjet-printer-201401w-1.0.0-1lsb3.2.x86_64.rpm, converted it to tar.gz using `rpm2targz`, unpacked and copied to /opt/epson-inkjet-printer-201401w/. However printer doesn't work. There is also epson-inkjet-printer-201401w-1.0.0-1lsb3.2.src.rpm on the above page which contains source code for /opt/epson-inkjet-printer-201401w/cups/lib/filter/epson_inkjet_printer_filter. I downloaded it and modified source code so it includes code saving debug info into file, ran `make` within src folder and copied newly compiled file "epson_inkjet_printer_filter" to /opt/epson-inkjet-printer-201401w/cups/lib/filter/. I also created folder debug with 777 access mode within that folder for storing debug file. Function load_core_library() on line 163 of file "src/raster_to_epson.c" was modified to included debug info:
| Code: |
static int load_core_library (HANDLE * handle)
{
debuglog(("TRACE IN"));
FILE *f = fopen("/opt/epson-inkjet-printer-201401w/cups/lib/filter/debug/load_core_library.txt", "w");
HANDLE lib_handle = NULL;
int error = 1;
ppd_attr_t * attr = NULL;
EPS_RES_FUNC resFunc;
char library [PATH_MAX];
do {
attr = get_ppd_attr ("epcgCoreLibrary", 1);
if (attr == NULL) {
fprintf(f, "get_ppd_attr is NULL\n");
break;
}
fprintf(f, "library: %s/%s\n", CORE_LIBRARY_PATH, attr->value);
snprintf(library, sizeof(library), "%s/%s", CORE_LIBRARY_PATH, attr->value);
lib_handle = dlopen(library, RTLD_NOW /*, RTLD_LAZY*/);
if (lib_handle == NULL) {
debuglog(("Failed to dlopen(%s)->%s", attr->value, dlerror()));
fprintf(f, "Failed to dlopen(%s)->%s\n", attr->value, dlerror());
fprintf(f, "dlerror: |%s|\n", dlerror());
break;
}
/* Setting of library function */
epcgInitialize = (EPCGInitialize) dlsym (lib_handle, "epcgInitialize");
epcgRelease = (EPCGRelease) dlsym (lib_handle, "epcgRelease");
epcgGetVersion = (EPCGGetVersion) dlsym (lib_handle, "epcgGetVersion");
epcgSetResource = (EPCGSetResource) dlsym (lib_handle, "epcgSetResource");
epcgGetOptionList= (EPCGGetOptionList) dlsym (lib_handle, "epcgGetOptionList");
epcgGetChoiceList= (EPCGGetChoiceList) dlsym (lib_handle, "epcgGetChoiceList");
epcgSetPrintOption= (EPCGSetPrintOption) dlsym (lib_handle, "epcgSetPrintOption");
epcgGetPageAttribute= (EPCGGetPageAttribute) dlsym (lib_handle, "epcgGetPageAttribute");
epcgStartJob= (EPCGStartJob) dlsym (lib_handle, "epcgStartJob");
epcgStartPage= (EPCGStartPage) dlsym (lib_handle, "epcgStartPage");
epcgRasterOut= (EPCGRasterOut) dlsym (lib_handle, "epcgRasterOut");
epcgEndPage= (EPCGEndPage) dlsym (lib_handle, "epcgEndPage");
epcgEndJob= (EPCGEndJob) dlsym (lib_handle, "epcgEndJob");
if (epcgInitialize == NULL

|| epcgRasterOut == NULL
|| epcgEndPage == NULL
|| epcgEndJob == NULL) {
debuglog(("Failed to dlsym"));
fprintf(f, "Failed to dlsym\n");
break;
}
resFunc.size = sizeof(EPS_RES_FUNC);
resFunc.memAlloc = memAlloc;
resFunc.memFree = memFree;
resFunc.getLocalTime = getLocalTime;
resFunc.resOpen = resOpen;
resFunc.resRead = resRead;
resFunc.resSeek = resSeek;
resFunc.resClose= resClose;
debuglog(("Model name : %s", PPD->modelname));
error = epcgInitialize (PPD->modelname, &resFunc);
if (error) {
fprintf(f, "epcgInitialize() failed\n");
break;
}
} while (0);
if(error && lib_handle) {
dlclose (lib_handle);
lib_handle = NULL;
}
*handle = lib_handle;
debuglog(("TRACE OUT=%d", error));
return error;
}

Now after trying to print test page from cupsd web interface (localhost:631) I have this:
| Code: |
# cat /opt/epson-inkjet-printer-201401w/cups/lib/filter/debug/load_core_library.txt
library: /opt/printer/lib64/libEpson_201401w.so.1.0.0
Failed to dlopen(libEpson_201401w.so.1.0.0)->(null)
dlerror: |(null)|
|
As you can see dlerror doesn't provide any information and returns null. Please advice on how to use this printer.[/url] |

Hi ilya1966616,
Had similar problem with Epson XP-750.
Epson uses "lsb" which Gentoo doesn't use.
To make Gentoo compatible you need to run as root | Code: |
ln -sf /lib64/ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3 |
This will make Gentoo lsb3.2 compatible.
Good luck.
Gerard.

| Unfortunately it didn't help. What other things I can do to make system lsb compliant? By editing source code of filter itself I discovered that the function that fails is "epcgStartJob". But I cannot debug further because this function is from dynamically loaded shared library for which no source code available. |

| I installed debian in VirtualBox and successfully printed from it. However it is inconvinient this way and I cannot install debian as main system because for some reason it has issues with my hardware during installation and shows disk access related errors. |

I used the debian file and unpacked it with deb2targz.
I first tried to install it using rpm directly but it failed.
After having installed the printer in cups it wouldn't print.
I forgot what error it threw.
I then googled and found the lsb3.2 thing.
After that it printed OK.
Sorry I can't tell you more.
Gerard.

Can you tell what exactly you found when googling? The script to make system lsb3.2 compliant or what? Did you save URL? |

Messing around with those legacy epson drivers will be painfull, I guess.
Have an eye on gutenprint (gimp-print). Maybe there will be support for your printer in its next release. From your link I conclude that L132 and L310 could be compatible to some degree and support for L310 seems to be coming. |

Hi ilya1966616,
I did not save the URL of this forum post.
As I remember I managed to make cups see my printer.
But when I sent a print command I got a cups error,forgot what it was.
And then after installing the link it printed OK.
The link concerns ld (load) which should be compatible with the software it loads!
I have the latest gutenprint installed also and checked the xml file of supported printers but no XP-750
or L132 or L310.
Maybe you should clean all of cups and start over again.
Gerard.
Edit:
grumblebear,these are NOT legacy drivers,far from it.
Epson used to have a website with nonWindows software but it was discontinued.

gutenprint is the solution. After emerging it select "Epson L210 - CUPS+Gutenprint v5.2.12 (color)" as the driver. |
