Auto cut on thermal printer (php) -


how can perform auto cut on epson tmt82 php file? bellow config file.

config:

$tmpdir = sys_get_temp_dir(); $file = tempnam($tmpdir, 'ctk'); $handle = fopen($file, 'w'); $condensed = chr(27) . chr(33) . chr(4); $bold1 = chr(27) . chr(69); $bold0 = chr(27) . chr(70); $initialized = chr(27) . chr(64); $condensed1 = chr(15); $condensed0 = chr(18); $data = $initialized; $data .= $condensed1;

printing: 

fwrite($handle, $data); fclose($handle); copy($file, "//localhost/printer");  # printing unlink($file)

try write chr(29) + 'v' (or chr(86)), , values m , n, depending on exact function want use per manual below (if want cut without feeding @ all, want use function a, means can follow 0 (or 48, not sure why mentioned both numbers in manual...!?), so:

chr(29) . "v" . 0

(you need logged on read reference, registering free)

edited: chr() code 'v' 86, not 56

edit2: comment on matt gibson said; chr(27) . chr(105) should work on model (just checked, chr(27) . chr(109)), it's obsolete command, should using chr(29) . "v". in case, printers receive these sorts of commands on own instead of having them along rest of string.

once right, should define variable type of cut want. ex. $cutpaper = chr(29) . "v" . 0;

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
