Please send me the bug file so as to isolate the issue.
I am also having the problem that pdf printing stops when graphics are
present. I am experiencing this since I upgraded to 10.3, 64bit kernel, and
new 64 bit AMD 64x2 CPU and ASUS mainboard. Under 10.2, a 32 bit kernel,
Pentium 4 CPU and Acer MB, the same printer (a samsung CLP-510) worked
In my case, I am not convinced that the problem is stemming from Adobe Reader,
as HTML pages also have this problem of stopping printing on pages with
I have been able to effect a work-around, using KPDF, and in it's print dialog
PDF Options tab selecting Force rasterization. When I do this, I am able to
print complete documents containing graphics. No other PDF viewer (and I've
installed most of the ones available in the various repositories were able to
print graphics pages.
The one issue that seems most significant to this user is that when printing
was working under 10.2, it was working in conjunction with Samsung's unified
driver. At that time, the CLP-510 was recognized by the samsung driver to be
on the USB port /dev/mfp4. YAST and CUPS seemed to be getting their printer
config info from the Samsung driver, as they were set-up in those services
after the samsung driver was installed.
With 10.3, the Samsung driver is unable to detect the samsung printer on any
USB port. Yast, on the other hand, detects and configures the printer on
usb://Samsung/CLP-510, and limited printing functionality is then
established. Afterward, when I invoke samsung's unified driver configurator,
I can see the clp-510 available to the driver on the URI:
usb://Samsung/CLP-510. However, the unified driver fails when attempting to
test the printer, by failing to detect the printer on the specified usb port.
In fact, the unified driver only displays (for configuration) usb
ports /dev/mfp0 through /dev/mfp11.
It seems that the printer's own driver being unable to see the printer is a
bit of a smoking gun. I'm not having much luck trying to troubleshoot the
printer configuration in YAST. I'm guessing that usb://Samsung/CLP-510 is
some kind of alias? I can't find any hint of it in the filesystem.
