Instance Method Summary (collapse)
-
- (Boolean) Abort
Abort function.
-
- (Object) AddQueue(queue_name, is_default_queue, default_paper_size)
Add new queue or overwrite existing queue.
-
- (Object) AutodetectPrinters
Try to autodetect printers by calling a bash script which calls “lpinfo -l -v” and processes its output and stores the results as YCP list in a temporary file and then read the temporary file (SCR::Read) to get the YCP list of #autodetected_printer_map.
-
- (Object) AutodetectQueues
Autodetect queues by calling a bash script which calls “lpstat -v” and processes its output and stores the results as YCP list in a temporary file and then read the temporary file (SCR::Read) to get the YCP list of #autodetected_queue_map.
-
- (Array) ConnectionItems(connection_filter_string)
Create a list of items from the autodetected connections which is used for the SelectionBox in the BasicAddDialog and BasicModifyDialog.
-
- (Object) CreateDatabase
Create the PPD database by calling a bash script which calls “lpinfo -l -m” and processes its output and stores the results as YCP list in a temporary file and then read the temporary file (SCR::Read) to get the YCP list of #printer_ppd_map.
-
- (Object) DeleteQueue(queue_name)
Delete queue.
-
- (String) DeriveDriverFilterString(driver_filter_input_text)
Derive a reasonable driver_filter_string from an arbitrary driver_filter_input_text.
-
- (String) DeriveModelName(description, max_words)
Derive a reasonable model info from an arbitrary description string.
-
- (Object) DetermineDriverOptions(queue_name)
Determine driver options by calling a bash script which calls “lpoptions -l” and processes its output and stores the results as YCP list in a temporary file and then read the temporary file (SCR::Read) to get the YCP list of #autodetected_queue_map.
-
- (Array) DriverItems(driver_filter_string, preselection)
Create a list of items from the PPD database entries which is used for the SelectionBox in the BasicAddDialog and SelectDriverDialog.
-
- (Array) DriverOptionItems(selected_keyword, selected_value)
Create a list of tree widget items from the driver_options which is used for the tree widget in the DriverOptionsDialog.
- - (Object) main
-
- (Object) Modified
Data was modified?.
-
- (String) NewQueueName(proposal)
Create a valid new queue name.
-
- (Object) QueueItems(local, remote)
Create the list of queues for the Table in the OverviewDialog.
-
- (Object) Read
Initialize printer configuration (checks only the installed packages) see en.opensuse.org/Archive:YaST_Printer_redesign#Basic_Implementation_Principles: for background information.
-
- (Object) RunHpsetup
Run hp-setup: because there is no usable exit code of hp-setup (always zero even in case of error).
-
- (Object) TestClientOnlyServer(server_name)
Test whether or not a “client-only” server is accessible.
-
- (Object) Write
Finish printer configuration (does actually nothing except to exit verbosely) see en.opensuse.org/Archive:YaST_Printer_redesign#Basic_Implementation_Principles: for background information.

Fun Printer Pro 1000 XL # After at least one words which contains only letters (the manufacturer name) # there are none or up to two words which contain only letters and hyphens (the model name) # and then there is a word which contains at least one number (the model series). # Therefore the manufacturer and model sub-string can be assumed to be: # One word which contains only letters, # followed by at most two words which contain only letters and perhaps hyphens # finished by one word which may start with letters and hyphens # but it must contain at least one number followed by whatever characters. # It is crucial to take whatever (trailing) character in the model series into account # to be on the safe side to distinguish different models # (e.g. "HP LaserJet 4" versus "HP LaserJet 4/4M" or "Kyocera FS-1000" versus "Kyocera FS-1000+"). # For example as egrep regular expression: # lpinfo -m | cut -d' ' -f2- # | egrep -o '^[[:alpha:]]+[[:space:]]+([[:alpha:]-]+[[:space:]]+){0,2}[[:alpha:]-]*[[:digit:]][^[:space:]]*' # Of course this best-guess is not 100% correct because it would result for example # that "ACME FunPrinter 1000" and "ACME FunPrinter 1000 XL" are considered to be the same model # but "ACME FunPrinter 1000XL" and "ACME FunPrinter 1000 XL" are considered to be different models. # The latter results no problem because the special sorting is only done # when all entries in the driver_items list seem to belong to the same model. # But the former results a small problem because the special sorting is done here # for different models with similar names. # To mitigate such problems, the special sorting is only done # when the driver_items list is short so that the user can easily survey the whole list. # For example the PPDs in openSUSE 10.2 # lpinfo -m | cut -d' ' -f2- # | egrep -o '^[[:alpha:]]+[[:space:]]+([[:alpha:]-]+[[:space:]]+){0,2}[[:alpha:]-]*[[:digit:]][^[:space:]]*' # | sort -f | uniq -i -c | sort -n # results that the maximum lenght of the driver_items list for the same model is 13 #
