1, open the software
2, into the editing to complete the preparation of printing status
3, click to print, in the pop-up dialog box click on the Properties
4, click on the volume in the property bar
5. Change the mode to heat transfer in the option of the volume, and then confirm the printing.
Note: before modifying this option

operate on the built-in TSC in the CPU. TSC is time Stamp Counter, a 64-bit timestamp counter provided for Pentium series CPUs, which is counted once per instruction cycle after the CPU is power up or reset, and Intel guarantees that the TSC overflow period is greater than 10. Like the 300MHz CPU we use, its TSC accur
1. Time-related hardware
The time in computer systems is mainly provided by three clock hardware: Real TimeClock, RTC), programmable interval timer, pit), timestampCounter, TSC ). These clock hardware provide clock square wave signal input based on fixed frequency crystal oscillator.
Generally, the Linux kernel requires two types of time:
The first type is the incremental clock in one step without sending interruption. The software needs to actively r
Problem 1: multiple calls to getsystemtime/getlocaltime within 15 ms (the corresponding function in Java is system. currenttimemillis (), and the same value is returned.
Solution: Use getsystemtime as the baseline, and use the high-precision timer queryperformancecounter provided by Windows (the corresponding function in Java is system. nanotime () for timing. The precise clock is baseline + timer time.
Question 2: queryperformancecounter/queryperformancefrequency
This problem mainly de
Check the memory information, CAT/proc/meminfo. Similarly, check the CPU information. CAT/proc/cpuinfo sometimes has such questions. For example, if the 4-core CPU is a 2-core CPU * dual-core, or 1 CPU * quad core? There is a simple method: the number of processor, the number of cores, and the number of CPUs, depending on the physical ID + 1 of the last Processor
For example:
processor : 0vendor_id : GenuineIntelcpu family : 6model : 23model name : Pentium(R) Dual

-Next. Therefore, clock_gettime and clock_nanosleep are two key APIs to port javasictest to other operating systems. It depends on whether the corresponding APIs can be called in other operating systems. Let's take a look at the implementation of clock_gettime in the Linux kernel. For details, refer to clock_gettime.c: If clock_realtime is used, it puts the gettimeofday call time into the struct timeval variable and converts it to struct.
Timespec type (the timeval
There are many types of Linux clocks, roughly divided into two categories: periodic clocks that provide interrupts (RTC, Pit, and so on) that provide a count of incremental clocks (such as TSC)Here is a brief list of several common.(1) RTC(2) TSC(3) Kvm_clock(4) ACPI_PMView current system-supported clocksCat/sys/devices/system/clocksource/clocksource0/available_clocksourceView the currently used clockCat/sy
