Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

HP Laserjet Pro M148f-M149f printer is designed in such a way that we do not have an option to turn off the sleep mode.

I suggest you do a Hard Reset

• (1) Turn the printer on, if it is not already on.
• (2) Wait until the printer is idle and silent before you continue.
• (3) With the printer turned on, disconnect the power cord from the rear of the printer.
• (4) Unplug the power cord from the wall outlet.
• (5) Wait at least 60 seconds.
• (6) Plug the power cord back into the wall outlet.
• NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
• (7) Reconnect the power cord to the rear of the printer.
• (8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

Assign Manual IP to the printer using the below steps:

1) Print a Network configuration page from the printer's control panel. 

2) Look for IP address from the Network configuration page. 

3) Open web browser - Chrome or IE or any other browser that you are using. 

4) Type the IP address mentioned on Network configuration page into the browser's address bar or URL bar and press enter button. 

5) Go to the Network tab. 

6) Click on Networking from the left pane. 

7) Then click on Network Address (IP). 

😎 Click on Manual IP Address and go to suggest a Manual IP. 

9) Scroll down the screen and select Manual DNS server. 

10) Enter the Primary and secondary DNS server from the Network Configuration page into the Manual Preferred DNS server field. 

11) Click on Apply. 

Refer to the video link for step by step instructions - http://hp.care/2cqpl6p 

• Note: The video is for win 8 but steps are similar for other operating systems as well. You need to enter the IP address in the browser's URL or the address bar to access the printer page.

Then, create a TCP/IP Port:

1. Search Windows for devices, and then select "Devices and Printers" In the list of results.

2. Right-Click the name of your printer, and then select Printer Properties.

3. Click the Ports tab, click on "Add port" select "Standard TCP/IP Port" and click "New Port"

4. Click next on the Add Standard TCP/IP printer port wizard, enter the printer IP address and click next and then click on "OK".

5. Now under the "Ports" tab you will find the Newport with the printer IP address, click "Apply" and "OK".

6. Restart the computer.

Check if you can print when the printer is in sleep mode.
