Hi VikingOSX and Grant Bennet-Alder.
Thanks for the replies, but unfortunately, they do not work.
The solutions you suggest are all OK for 10.7.x (and I have used them before), but these steps do nothing in 10.8.2. No difference at all.
I have also tried various other suggestions I found on the web and in this forum, such as:
- cupsctl BrowseRemoteProtocols=cups
- cupsctl BrowseProtocols='"cups dnssd"'
They all seems to work (and I needed them before in 10.7.x), but they don't seem to help any more in 10.8.2
To illustrate the problem, I have tested the following 4 cases (in this particular order) on iMac 10.8.2 through CUPS web browser leding to teh following (copied text from CUPS web interface):
Step 1:
Description: EPSONserver
Location: server
Driver: Local Raw Printer (grayscale)
Connection: http://192.168.1.94:631/printers/R285
Defaults: job-sheets=none, none media=unknown
Jobs
▼ ID ▼ Name User Size Pages State Control
EPSONserver-23 Unknown Withheld 1k 1 processing since Sat Oct 6 14:59:57 2012 "Printing page 1, 85%"
Result step 1:
Test page: via CUPS web browser, OK. works just fine, full color and everything looks just fine
Printer in printer list: No, installed printer not available in OSX.
Can print from application: No, printer not in printer list. Cannot select printer.
Step 2:
Description: EPSONserver
Location: server
Driver: EPSON SP R285 Series (color, 2-sided printing)
Connection: http://192.168.1.94:631/printers/R285
Defaults: job-sheets=none, none media=na_letter_8.5x11in sides=one-sided
Jobs
▼ ID ▼ Name User Size Pages State Control
EPSONserver-24 Unknown Withheld 1k Unknown stopped "Filter failed"
Result step 2:
Test page: via CUPS web browser: NO. "Filter failed"
Printer in printer list: YES
Can print from application: NO, "Filter failed".
Step 3:
Description: EPSONserver
Location: server
Driver: Generic PostScript Printer (color, 2-sided printing)
Connection: http://192.168.1.94:631/printers/R285
Defaults: job-sheets=none, none media=na_letter_8.5x11in sides=one-sided Jobs
Result step 3:
Test page: via CUPS web browser: low resolution/bad quality, black and white test page
Printer in printer list: YES, it remained in printer list when changed from step 2 to step 3.
Can print from application: Yes, but bad quality, not useful at all.
Step 4 = change settings back to step 1 :
Description: EPSONserver
Location: server
Driver: Local Raw Printer (grayscale)
Connection: http://192.168.1.94:631/printers/R285
Defaults: job-sheets=none, none media=unknown
Result step 4:
Test page: via CUPS web browser: OK. works just fine, full color and everything looks just fine
Printer in printer list: it disappeared from the printer list at the moment the changes back from step 3 to step 1 were activated.
Can print from application: No, printer not in printer list. Cannot select printer.
Overall conclusion:
The printer appears in the printer list only when it is a postscript printer or using manufacturer drivers (i.e epson drivers). It does NOT appear when using a RAW printer (but works fine printing test pages through the CUPS web interface).
10.8.2. seems to have a serious bug.
Any help? Or is downgrading to 10.7 my only solution?
